Can someone tell show me how to do this.

Show the product as a sum or difference

sin 6x cos 2x

  • PreCal -

    (sin6x)(cos2x)

    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
