Is there any way we can get maple to tell us which variable we are recursively assigning?
I would like to simplify
sin(4*pi*w)/sin(2*pi*w)
The answer I am looking for is 2*cos(2*pi*w).
Does anyone have an idea how to do this is Maple? Some earlier version of Maple I used could do this,
simplify( sin(4*pi*w)/sin(2*pi*w) ) = 2*cos(2*pi*w)
There a plenty of different trigonometric representations for the answer, so my hypothesis is that I should somehow tell to Maple which I am looking for.
For example
Gives
Which is better, but still not the answer I am looking for

Using numerical methods, I cannot calculate the derivative of sd with respect to r at r = 2 and t = 4.

Does anyone know how to enter in the pdsolve function Dirichlet conditions and Neumann values?

I am reading the help page for "time" and it says that it will display the time elapsed since the maple kernel was loaded, but I just want output that is the value of the time and date displayed on my computer at the point the input in the command line is exrcuted. How do I do this?
Hi,
I am struggling with one task involving solve and plot commands. I would appreciate if I could get some help. What I need to do is as follows:
1. Define alpha between 0 and 1.
2. Solve an equation f(x,alpha) =0 for x by taking different values of alpha.
3. Of all values of x obtained in step 2, choose the value of x between 0 and 1 and discard all others. I have technically shown that there will be exactly one value that is acceptable and all other values of x can be discarded.
4. For different values of alpha and correspondingly selected values of x in step 3, plot and display function g(x,alpha) with function value on the vertical axis and alpha on the horizontal axis.

Hi,
does anyone remember of a recent question (maybe a post) about a bouncing ball over a hilly ground?
I can't put the finger on it.
TIA
f(x) := piecewise(0 < x, x^(3/2)*sin(1/x), x = 0, 0, undefined);
plot(f(x));
gives me the following error:
Error, (in plot) incorrect first argument piecewise(0 < x, (HFloat(2.739493386336394e116)+HFloat(2.739493386336394e116)*I)*x^(3/2), x = 0, 0, undefined)
I just want to see the function plot. With Wolfram Alpha this is no deal at all!
I used the implicit function to draw two images, how to display only the intersection of two images? Or, how do I draw the x^2+y^2+z^2=1 image under x+y+z=0 condition? Code show as above.Thank you.
Is it because I have handed subs a multiset or is it because I used the "``" things in the code producing my set? I seemed to remember algsubs and subs working perfectly well regardless of the dimensions of the argument in previous times i have needed it.

Why Maple returns 1/x as singular solution below when this solution can be obtained from the general solution when constant of integration is zero?

How can I get a seq(seq(...))) to print each subsequence per line? It currently prints all the sequences as one big sequence. I'd like some way to tell it to "eol".
