Can someone tell show me how to do this.
Show the product as a sum or difference
sin 6x cos 2x
You will need to use the double-angle identities to expand both sin6x and cos2x.
As a hint, you will have to use sin(3*2x) for the double-angle of sine.
If you want to work on that, then we can critique your thinking.
ok thanks I'll work on that
