## Calculate angles of incidence/reflection...

What would be the simplest method using maple to calcualte the angles of incidence/reflection of straight lines from a common point striking the internal surface of a circle. If the centre of the circle lies on the y-axis and circumference touches x-axis forming a semi circle. Is it possible to represent graphically the setup and also have calculations giving accurate reflected rays from the surface of the curve, for the various points along the x-axis. Thanks

Hi, I am solving a question about derives. I now what's the value of dx/dt, x and y. I was asked to calculate the value of dy/dt. This is my Maple worksheet:

## Beginner's question: Can Maple simplify 3x+3y into...

Hello everybody, I'm just trying to get familiar with Maple and I'm wondering if it would be possible to transform an expresion like: 3*x+3*y into 3*(x+y). Many thanks in advance, Ruben

## Simplification of preexponential terms after convo...

Dear all, i want to do some pharmacokinetic calculations with the convolution intergral. E.g. the input rate into the linear system is Inpfunc:=t-> a*exp(-k*t)+b*exp(-m*t); the system impulse response is Transfunc:=t->c*exp(-u*t)+d*exp(-v*t)+e*exp(-w*t); When i compute the system response to the input rate function as Respf:=int(Transfunc(t-tau)*Inpfunc(tau),tau=0..t); I do obtain a huge mess of exponentials. With the 'collect' function i collected the preexponential terms but they were still huge (abt. 4 screens full). I have tried 'factor', 'symplify' and so on but all commands

## plotsetup in jsp pages...

Hi, By default it seems that using plot in the maple:statement tag in a jsp page creates jpegs. Is there a way, via plotsetup or otherwise, to create images in different formats? Thanks.

## How to output in engineering notation...

Hello all! How can I get Maple 10 to output it's numbers using engineering notation (milli, micro, Mega, Giga, etc) instead of indices? Thanks --Amr

## Piecewise with more than 2 conditions using 2D Inp...

Hello everybody, I was going through the manual and I'm having difficulties trying to replicate the example on Adding Custom Distributions (Section 4.6 under Probability Distributions and Random Variables). I cannot replicate the piecewise function using 2D Input. I can only type the first 2 conditions. I know it can be done in 1-D with the piecewise command but I'd like to use the other way. Any suggestions would be greatly appreciated. Regards, Ruben

## solve a recursive equation in 2 variables...

Hi Maplers: I'm probably spoiled, but maybe Maple can actually solve the following type of problem and I just haven't figured out how. Solve a recursion equation in two variables: f(m+1,n+1) = some expression involving combinations of f(m,n) etc. I am impressed with "rsolve" that magically finds solutions to f(m+1)=... i.e. a single variable. With great effort I have managed to figure out my 2-variable problem using generating function techniques, but perhaps Maple can do the whole thing in one great big single step. Does anyone know if such a thing exists? I can't find anything in the Help.

## Latex Export...

Hello, I'm trying to export a worksheet in LaTeX format. It gives me a .tex file which requires a package maplestd2e.sty (not maple2e.sty) which I don't have. I found a file called maple2e.sty at http://www.maplesoft.com/support/downloads/latex_patch.aspx and it works up to a point. Firstly I had to change the output tex file to require package maple2e.sty and more importantly it has equations running off of the edge of the page. Please help, Regards, A. Carmichael

## numerical differentiation / fdiff...

Is there a way to use fdiff for functions, which allow only numerical input? It seems that fdiff is sending symbolics and that would not work in my case of interest (and I want to avoid to code such stuff, especially how to get the appropriate step size automatically ...). Related to Maple I only find this (general) source, but no according paper: M. Monagan, E. Cheb-Terrab A numerical differentiation routine for computing single, multiple and partial derivatives to arbitrary precision. This enables us to compute numerical values of derivatives of special functions for whic
