How can one print the output from the statements executed within a loop as the loop outputs only the last calculation.

I was wondering if anyone could tell me how to plot the direction field of a differential equation. I'm trying to plot ty'+2y=sint. If anyone could give me some advice, that'd be great.

I'm using the cosine function and just read in the help section that the trig functions only take arguments in radians. Is this true ? Is there no way to use arguments in degrees for the trig functions ? v/r, Dan

Hi, If a sentence (as a string) is given with uneven number of spaces in it, how can we smooth it out so that every word is followed by exactly one space. I think this would be solved by Regular Expression in patmatch, but exactly I don't know. Kindly help me. Thanks.

i have two function f(x) and g(x) and i wanna plot them in one plot x=1200..2300, but for f(x) y=0..600 and for g(x) y=0..50. How can i display different scaling y-axis?

Hi, I would like some help with plotting a 2D and 3D graph together. I actually have an equation with two varying parameters and I have displayed a 3D plot.What i want is to set a value for the one parameter and plot the line together with the previous surface, so that I can see where this line is placed on the surface.I provide the example to make myself clearer. Itouch50 := -0.4058074876e13*sqrt(1.+h)/(sqrt(ts)*(-500000000.0*ln((625.+125.*h+25.*h^2+5.*h^3)/h)* sqrt(1.+h)+587311661.7)) Itouch := 474335.0379*h*(10300.*2.718281828^(-3.703703704*ts)+1030.*2.718281828^(-3.703703704*ts)* h+490.*2.718281828^(1/(5.*ts+6.))+49.*2.718281828^(1/(5.*ts+6.))*h)/(51200.*sqrt(ln(100.*h))*h+5120.*sqrt(ln(100.*h))*h^2+25600.+12790.*h+511.*h^2)

Hello, I have never used Maple before and I am working on an assignment but unfortunately class ended before I could ask my professor with some help so I was hoping someone on here might be able to help me out. All I need to do is get the first equation to look like the second equation, I would use the simplify command but I cannot break apart the l(l+1), can anyone help me out?

Equation 1:


Need it to look like this:

I want to tell maple that func is a function of x, y, z, but I don't know what the function is. This is so when maple evaluates derivatives, etc, it won't assume 'func' is a constant. ie: instead of func := (x,y,z) -> x^2 + 2y + 3xyz; I just want to say func : = (x,y,z); so that when I ask for a derivative, maple just prints out 'diff(func, x, 1) etc, where 'diff(func, x, 1) means the first partial deriv of x. I hope that's clear enough for all you experts out there. I am a newbie to Maple. I tried func : = (x,y,z); but it did not seem to work for me.... Thanks in advance,

Hello. I was wondering if it is possible to unassign a variable from within a procedure. The accompanying file illustrates what I am trying to do. As always, my anticipated thanks to anyone kind enough to take the time to help me. I would be totally lost in MAPLE without this forum. a href='http://maplenet.maplesoft.com/maplenet/worksheet/mapleprimes/2292_Unassign within a procedure.mw'>View 2292_Unassign within a procedure.mw on MapleNet or Download 2292_Unassign within a procedure.mw

Hi, Is there an easy way to convert Matlab or C code to something that Maple can use? I know CodeGeneration in Maple can go the other way, but can't import into Maple. Thanks! Andy

I wonder who could help me to became a Maple TA v.3 Beta_Tester? Thanks in advance Ivan Weinem iweinem@yahoo.com.br

Hi, I'm new to maple and I would like to draw a plot of a time-dependent 2D Vectorfield and some trajectories: 1. I have the field udep := (x, y, t) -> cos(t)*x - sin(t)* (-y); vdep := (x, y, t) -> sin(t)*x + cos(t)* (-y); it looks like this: 2. now i would like to draw a trajectory T that has at every point a tangent parallel to the field (to show the path of a massless particle inside this field)

Hi, Separation of variables has been driving me nuts again, By applying the method of separation of variables solve: ux + uy =0 Separate the variables: fp1 := diff(u(x, y), x) = -(diff(u(x, y), y)); pdsolve(fp1, u(x, y)); u(x, y) = _F1(y - x) is this the correct solution? u(x,y):= _F1(y-x) If it is, what is the _F1? If it is not the solution can someone explain the correct solution to me? Regards malt

I wonder if someone could help explain to me how to use Matrix equations. Suppose A is a 3x3 matrix of constants, b a 3 vector of variables (x,y,z) and c a 3 vector of constants. The equation A.b = c is really 3 equations in x y z. Is it possible to extract those equations from the matrix equation A.b = c? I explain my question more clearly in the uploaded worksheet. Thanks The link can be found in the File Manager Vie

There is a discontinuity at 0, but discont gives no answer: discont(1/sin(abs(x)),x); Any idea?
