So I'm trying to do a question in Maple and I'm beyond lost. I've used it before but a different version and Maple 12 is confusing as is the syntax. Anyways, the question is: In one ty-graph plot the solutions of y' = cos(pi*ty) for a sequence of 21 equally distributed initial points y(0) between 0 and 4. I figured that I have to use dsolve and I wrote: >ode:=diff(y(t),t)=cos(pi*t*y(t)) which works fine Then, I did >dsolve(ode) But it doesn't give me an answer and just jumps to the next line. I looked at the help file but found no answers (maybe I wasn't looking hard enough). Then I figured maybe I had to do the entire thing at once, got rid of dsolve(ode) and wrote: >seq(dsolve(ode), t=1..4, 0.2) But Maple said: Error, invalid input: diff received 1, which is not valid for its 2nd argument. Can anyone give me any hint as to what to do?
