I have 3 lists of numbers, i need to plot a 3d grpah of these lists, is this possible in maple?

Hello, I need to approximate the Wavelet transform of a set of data, and then plot the 3d graph, I need to find the integral

w := sum(0.25e-2*f[m+1]*g(0.25e-2*m), m = 0 .. 71999):

with varying values of tau and s. I have recieved some help but i think the method of using lists is wrong (one lecturer told me to do this but the another said it wouldnt work.. and it doesnt), and the surface plot maybe wrong for what i need, this is what i have been helped to make so far,

Hello! I am 100% useless with maple and i need some graphs to fill a report i am doing.

I need two sine wave graphs with different frequencies, i can plot a sine wave but i dont understand how i am supposed to do this in terms of frequency?

I also need to plot fourier transforms of each of these sine functions and to apply a wavelet transform to them.

If anyone could help me with any of this i would be so grateful!! Or even just point me in the direction of a help guide because i am struggling to find anything that makes sense!!!
