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!!!

Thankyou for your time!
