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:
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
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
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.
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
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
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.
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
Hello, I'm finding, how to translate/customize Maplets from the Calculus1 (Maple 10.06) to different language (for students). Can anyone help me? Is any possibility to download source codes? Thank you very, very much!
I want to calculate a definite integral with a parameter S(assume S>0),which is as follows: The link can be found in the View 3216_how to calculate the difinite integral.mw on MapleNet or Download 3216_how to calculate the difinite integral.mw
View file details in maple 10 ,it always gives a trivial solution ,can it
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
Given is a sphere and a tetraeder. How can I (calculate and) plot the intersection of a plane with both objects? The intersection shoud be a circle and a triangle (in 2D or 3D). I tried a lot, but it didn't work out at all. The intersection command just works e.g. with two spheres. Many thanks for any help in advance!
I have solve the Legendre equation (1-x^2)y''-2xy'+alpha(alpha+1)y=0. The solutions are: y1=1-alpha(alpha+1)x^2/2! +alpha(alpha-2)(alpha+1)(alpha+3)x^4/4! +sum{(-1)^m [(alpha-1)...(alpha-2m+2)][(alpha+2)...(alpha+2m-1)]x^2m/(2m)!} y2=x-(alpha-1)(alpha+2)x^3/3!+(alpha-1)(alpha-3)(alpha+2)(alpha+4)x^5/5!+sum{(-1)^m[(alpha-1)...(alpha-2m+1][(alpha+2)...(alpha+2m)]x^2m+1/(2m)!} I tried to obtain a Legendre polynomial, say P5(x), with Maple'sum function by plugging in the general expression but I do not obtain the correct answer. Can someone indicate how this can be done. Thank you kindly.
Is it possible with Maple to make contour plot of a function defined by its values in 2D grid?
