Rewriting a combination of sine and cosine of equal periods as a single sinusoidal function provides an approach for solving some equations. Example 7 Solve . 3sin(2x) +4cos(2x) =1 to find two positive solutions. To approach this, since the sine and cosine have the same period, we can rewrite them as a single sinusoidal function. A =(3)2 +(4)2 =25, so A = 5 5 3 cos(C) = , so 0.927 5 3 cos 1...Rewriting a combination of sine and cosine of equal periods as a single sinusoidal function provides an approach for solving some equations.

### Sum and Difference Identities for Sine and Cosine Choose the correct steps to evaluate a trigonometric expression using sum and difference identities. Use step-by

- The biggest advantage to having three different identities for the cosine of a double angle is that you can solve for the cosine with just one other function value. The sum and difference identities for sine and cosine, on the other hand, as well as the double-angle identity for sine, all involve both the sine and cosine of the angles.
