### Is it possible to plot with symbols for x and y ticks?

I'd like to plot a function similar to something like: y= A*sin(w*x)
Something along the lines of

x = var('x')

w = var('w')

A = var('A')

y = A*sin(w*x)

assume(w>0)

assume(A>0)

Then be able to do:

plot(y(x=x), (x,-2*pi()/w,2*pi()/w)

And have sage plot the function, where for the x-axis the ticks would be something like (-2*pi/w, -pi/w, 0, pi/w, 2*pi/w)
and the y-ticks would look like (-A, -A/2,0, A/2, A).

Hopefully that makes sense? Is this possible?
