Homework Statement
Write sin(7t)-sin(6t) as a product of two trig. functions.
Homework Equations
e^(ix)=cos(x)+isin(x)
sin(2x)=2cos(x)sin(x)
cos(2x)=cos^2(x)-sin^2(x)
The Attempt at a Solution
I do not really know how to approach this. I have tried using the sin(2x) identity but I could not get the correct answer from it. Can anyone help?
