HP Prime: Ways to use the INPUT command (Version 6030)

Note: This is for HP Prime Software Version 6030 (2014 3 31)


The INPUT Command

On the HP Prime, the INPUT command can include various types of input forms: numeric fields, choose boxes, and check boxes. You can also restrict which types of input are accepted. This blog entry will cover some of the basic forms of INPUT. 

For a video on the subject, click here:  https://www.youtube.com/watch?v=qSY6RXvAHuw

Basic Form

INPUT(var, title, label);

var = can be one or a list
title = optional string
label = optional string, number of labels are equal to number of var

The example programs presented (except for IN4) win use one variable.

Here is an example of the basic format. Keep in mind, the title and label strings are optional.


EXPORT IN1( )
BEGIN
// Basic
INPUT(X, "Enter X");
RETURN √(1+X^2);
END;


Specifying Types

INPUT( {var, [types allowed]}, title, label);

Type numbers are surrounded in square brackets.

Common Types:
-1 All
0 real numbers
1 integers
2 strings
3 complex numbers
4 matrices
6 lists
8 functions
9 numbers with units
14.? CAS objects

IN2 and IN3 are programs that ask for a specific type. IN2 asks for a matrix (type 4) and IN3 asks for a list (type 6).


EXPORT IN2( )
BEGIN
// Ask for a Matrix
INPUT({{M0,[4]}}, "Matrix");
RETURN M0*TRN(M0);
END;



EXPORT IN3( )
BEGIN
// Ask for a List
INPUT({{L0, [6]}}, "List");
PRINT( );
PRINT("Σx ="+STRING(ΣLIST(L0)));
PRINT("mean = "+STRING(approx(mean(L0))));
PRINT("std dev ="+STRING(approx(steddevp(L0))));
END;


Checkboxes

INPUT({{var, n}}, title, label);

n groups the current and next n-1 checkboxes. If you want a checkbox next to each variable, let n = 1. A variable that is checked has a value of 1. Otherwise, the value is 0. Each variable and it's corresponding n are surrounded in curly brackets.


EXPORT IN4( )
BEGIN
// Checkboxes
INPUT( {{A,1}, {B,1}, {C,1}}, "Turn On Variables");
PRINT( );
PRINT("Number of Checks: "+STRING(A+B+C));
END;


If you want to use more than one input form, I advise to keep INPUT types separate.


EXPORT IN5( )
BEGIN
// Checkbox Modes
INPUT( {{M,1}}, "Check for Degrees");
HAngle:=M;
// Input Data
INPUT(A, "Angle");
PRINT( );
PRINT("SIN(2A)² =");
PRINT(SIN(2*A)²);
END;


Choose Boxes

This INPUT form will create a choose box (drop down list).

INPUT( {{ var, {choice0, choice1, choice2...} }}, title, label)

Follow this by:

IF var == 0 THEN choice0 instructions...(END;)
ELSE (if there are only two choices) or
IF var ==1 THEN choice1 instructions... END; and so on...


EXPORT IN6( )
BEGIN
INPUT( {{C, {"SI","US"} }}, "Units of g");
IF C==0 THEN
RETURN "g = 9.80665 m/s^2"; KILL;
ELSE
RETURN "g = 32.17404 ft/s^2"; END;
END;


That is some of the ways we can use the INPUT command on the HP Prime. To check out all of the ways INPUT command, including putting the prompts in specific places, check out the help screen for INPUT.

Retro-Review: Casio Algebra FX 2.0 Plus

Retro-Review: Casio Algebra FX 2.0 Plus

Production Period: 1999 - 2001 (thank you www.rskey.org)
Memory: 146,000 bytes with 768,000 bytes flash

On the surface, the Casio Algebra FX 2.0 Plus looks like a typical modern Casio graphing calculator: the MENU key displays an iconic menu, the top row is a set of six soft keys, the layout of the keys are similar, and its programming language is the same as its fellow graphic calculators.

I am just going to go over what separates the Algebra FX 2.0 Plus from the other Casio calculators. We can assume it can handle what ever the fx-9860g series (including the Prizm, sans color) does.

What separates the Algebra FX 2.0 from the other Casio graphing calcualtors? First, complex numbers are not only allowed as arguments in transcendental functions (logarithmic and trigonometric functions). Complex numbers are accepted as coefficient in the polynomial and simultaneous equation solvers. Second, instead of the usual 6, the polynomial and simultaneous equations solvers work orders up to 30. The big difference, is that calculator has CAS (computer algebraic system) capabilities.

Being Casio, the CAS functionality is accessed in a separate mode. Make that three separate modes.

With each CAS mode allowing equations, algebraic expressions, integers, and fractions to be expanded, factored, simplified, and approximated; the mode dictated which other options were available:

CAS Mode: This had the full suite of CAS functions on the Algebra FX 2.0 Plus: derivative, integral, sums, the ability to work with ∞, extracting parts of an expression, calculating arc length, tangent lines, GCD, and LCM. (I think I got most of it, it not all.)

Algebra Mode: This is a limited CAS mode, probably aimed at younger students. Only x!, |x|, denominator and numerator extraction, LCM, and GCD are available. Not sure what the Algebra mode exclusive arrange and replace commands do.

Tutorial Mode: Choose from a library of 45 equation types and use the CAS commands to solve them. What commands are available is dependent on the type of equation being solved.

Something I thought was strange with the CAS mode was that it could handle numbers bigger than 10^99. Try to get the approximation of that number, you get an overflow error. And really large numbers have digits cut off in the display so reading them presented a challenge.

For example: 80! (80! ≈ 7.1569 × 10^118)

Display: 7156945704626380229481(?) 6945704626380229481153(?)...

Trying approx(80!) returns an overflow error.

A impressive mode was the Differential Equation mode, where you can get a slope field plot of various types of equations including:
* 1st Order Linear
* 1st Order Bernoulli
* 1st Order Exact
* 2nd Order Linear and higher
* 1st Order Linear Systems

I bought my Algebra FX 2.0 I think more than a decade ago on clearance. I think this calculator was underrated due to its short production life. Was the Algebra FX 2.0 a predecessor to the ClassPad Series? Seems like it.


That is my retro-view. Hope you liked it. Talk to you next time!

PCalc and HP 50g: Mohr's Circle

Given shear stresses in the x and y directions (σx and σy) and normal stress (τ), find the radius, center, and viewing angle of Mohr's Circle.

I take τ to represent both τxy and τyx (both are assumed to be equal).

Radius:
R = √( (σx - σy)/2)^2 - τ^2 )

Center (S, 0):
S = (σx + σy)/2

Viewing Angle:
θ = atan( 2τ /(σx - σy)) / 2

fx-5800p Programs (can apply to Casio graphing calculators also, e.g. fx-9860g, Prizm)

This is a collection of programs I wrote on the Casio fx-5800p. These programs should also work on any Casio Graphing calculator (fx-9860g, fx-9750g, Prizm) since the programming language between Casio calculators remains largely the same.

Now if I can find my fx-5800p that I misplaced last night... *sigh*. Thank goodness for notes!

Notes for the fx-5800p programs:


There are no SIGN or MOD functions. Here are the work arounds I used (see SUN):

SIGN(x):
...
X > 0 ⇒ 1 → X
-X > 0 ⇒ -1 → X
...

n MOD d:
...
N - D Intg( N ÷ D ) → result variable
....

Table of Contents:

1. Rotation of (x, y) (ROTATEXY)
2. Law of Cosines (COSINES)
3. Pendulum: Period and Average Velocity (PENDULUM)
4. Arc Length of a Parabola (QUADLENGTH)
5. Position of the Sun (SUN)

Variables:
D = length of the step or bar holding the pendulum
L = length of the rod or string that is swinging
R = large radius of the circular ring

At the units, enter 0 for US units (set g = 32.174 ft/s^2), anything else for SI units (g = 9.80665 m/s^2).

Scientific Keyboard Challenge, Revisited

On this post:

http://edspi31415.blogspot.com/2014/05/scientific-calculator-keyboard-challenge.html,

I have issued a creativity challenge: design a scientific calculator using only 25 keys.  No restrictions.  I came up with a couple ideas.

Before I present mine, I want to show a great landscape design by Picky Bart.  Thanks for posting PickyBart!:

http://pickyb.blogspot.co.uk/2014/05/proposed-scientific-rpn-hp-quickcalc.html

The first one is an RPN keystroke programmable calculator:



The next one is a graphing calculator. (or at least an attempt at one).  Since only 25 keys are allowed, this prevents the use of an ALPHA key.  So, soft keyboards via dialogue had to be implemented instead.



Modes:
RPN/Linear/Math IO
DEG/RAD/GRAD
FUNC/POLAR/PARAM/SEQN
a+bi, r<q, REALS
BIN/OCT/DEC/HEX
Language (dialogue bar)
Data:  Edit, Name, Delete
Stat: n, Means, Sums
Dist:  Norm PDF, Norm CDF; iNorm, Bin PDF, Bin CDF, Pois PDF
Pois CDF, Chi PDF; Chi CDF, iChi
List:  { }, sum, average, prod; seq, sorta, sortd, augment;
Dchg, size, position
Regr:  Vars (a, b, c, r), Regr (Lin, Log, Exp, Pwr, Inv, Quad, Cubic,
Sine)
Matrix:  [ ], det, trans, eigen; eigvect, size, position, ref; 
rref, spec radius, rank, trace; LQ, LSQ, LU, QR
Prog:
File:  New, Edit, Delete
Input:  " ", Input, Prompt, Menu
Output:  Clear, Display, Output, Graph
Tests:  ==, >< , >, >=; <, <=, and, or
IFTE:  If, Then, Else, EndIf
Loop:  For, Step, Next; Repeat, Until, While, Wend
Ctrl:  Pause, Stop, Error, Subr
String:  length, sub, left, right; >expr, >string, position, augment
Math:
Frac:  PDQ, a b/c, exact, approx
Hyp:  (hyperbolic)
Prob: x!, nCr, nPr, gamma; rand, randint, randnorm, dice
Cmplx: abs, arg, real, imag; >Polar, >Rect
Parts: IP, FP, round
Calc:  derivative, integral, S, P 
Constants: (24)
Conversions: (12 pairs)
Base:  
Mark: b, o, h, d
HEX: A, B, C, D; E, F
Logic: and, or, not, xor; xnor, shift right, shift left, 2's
Utility:
RPN: swap, roll down, roll up, drop; over, pick, view, dupn
Solver: New, Edit, Delete, Solve
ALPHA: - enter message and press enter
CAPS (Keyboard), lower (keyboard), Symb (! @ # $ % ^ & * ( ) { } and math symbols), Greek 

I may have forgot something but I think I got all the basics covered.
