Hey all, my integration is a bit rusty so I'm having trouble with integrating a function thats something like:
sin(yx)sin(zx)dx
How would I go about a problem like that?
Assuming y and z are not functions of x, the integral is independent of these variables and y and z may be treated as constants. Then integration by parts (applied twice to get a multiple of the original integrand) makes short work of this integral.
Otherwise, you need to know those functions of x.
