Hi, I have a formula with variable unknowns, lets say p,q,r.

How do I get the answer giving me the output for different combination of input that I'm inserting?

For example : f(p,q,r):=(34p^9-7q)/r

Calculate when (p=2,q=8,r=7) and (p=3,q=0,r=3) and (p=4,q=1,r=9) and so on...

Please advice. Many thanks

I've made exam questions for students that they have to answer by doing some calculations in Maple.

I would like to let them copy the commands they used to a Maple TA text field.

However, the standard worksheet in our computer lab uses 2-D math. Copying this 2-D math to Maple TA works fine with "paste as plain text", but copying 1-D math also works with ctrl-v in Maple TA, which is more convenient for students under stress.

Since I am not allowed change...

I'm acquainted with using View - show/hide contents - and unchecking input to hide the input in a worksheet.  My problem is that I would like to do this only some of the time.  I've tried selecting just the text where I want to hide the input but the menu action seems to apply to the whole worksheet.  This is in Maple 14.  Is there someway to hide the input some of the time but leave it visible the rest of the time?

Hi there

I have, for a while, been trying to find a way to force maple to display the unit im inputting. 

Im studying to be an engineer, and for an example the unit i often would like displayed is kilonewtons per square metre (kN/m2). 

Once i hit enter, maple converts it to Pa, which isnt really usable for me ... 

The question is, is there any way to stop maple from doing the conversion in output......

Hey guys,

I have the function f(x) =(sin(x) + 1)/(x^2 + 1) where x =-Pi/2 and 3Pi/2

1) I first set up an intgral for the function:

Good Morning.

I have a problem

i have two functions

> xcir(t):=0.3 + 0.15*sin(t):
> ycir(t):= -0.3-0.15*cos(t):

and i suppose that i have a problem in the following equation

> qd2 := ((arctan(-ycir(t)/xcir(t))-arctan(.45*sin(qd3(t))/(.45+.45*cos(qd3(t)))))*180)/(3.1416);
> qd3 := 180*arccos((xcir(t)*xcir(t)+ycir(t)*ycir(t)-.45*(2*.45))/(.45*(2*.45)))/(3.1416);

A simple question, the answer of which is eluding me. How do you echo the input to the output without performing any processing (e.g. solving, simplifying, factorizing etc.) whatsoever?

Maple 13 here.

The help documentation talks about an "Input Display Drop-down List", likewise for Output. What "Input Display Drop-down List" ? ... I can't see this anywhere.

This is a question about how to read standard input in UNIX (bash).

I would like to write code in an easy to use editor (BBEdit) and use maple to take input from what other systems would refer to as STDIN or $stdin. The motivation for using an external text editor is to reduce the memory burden on the Maple editor in a program that rotates hundreds, hopefully thousands, of Maple points and other objects (See: http://www.mapleprimes.com/questions/123184...

Hi,

Was wondering why I am getting such a variety of outputs when I input what is essentially the same expression each time ?

See attached screenshot.

thanks,

In 2D input it is possible to represnet

diff(f,x) as d/dx f

Is it possible to do

diff(f,x,x) as d^2/(dx)^2 f somehow?

I am trying to make substitutions into a matrix using the subs() command, but it does not work.

for example

with(linalg):
A:= matrix([[a,b,c],[d,e,f]]):
B:=subs[inplace](a=1/L,b=-1/L,c=1,d=-1/L,e=L,f=1,A);

Hello

I would like to have an optional input value in my procedure. It could be of type string or numeric value.

Example:

bgp:=proc( x, y, z, optional) local bgp, A;

bgp:=Array(1..2);

bgp₁ :=pointplot3d([x, y, z]);

# if the optional value exists:

bgp₂ :=textplot3d([x, y, z, optional]);

A:=bgp₁;

# and if the optional value exists:

Hi,

I am new to Maple and doing a trivial calculation raised a few questions. I tried to calculate the average density of a wire with the following specs: 

• diameter = .40 inches
• length = 1000 feet
• weight = 61 pounds

Here's what I have come up with. 

with(Units[Standard]):

wirediameter:=.40[inch]:

wirelength:=1000[ft]:

wirevolume:=(wirediameter/2)2 * Pi * wirelength:= 

Hello again!

I am writing a procedure of which the body is done, I "only" need to take care of the input in a clever way, which is where I'm stuck. I want to make it as simple as possible for the end user. The procedure has the following parameters:

- 2 matrices of type 'Matrix' [required], say A and B

- either a list L (default []) or a symbol S (but one of them is required)

- an optional symbol v::symbol:=t

What's the best way of handling these?
