![Tutorial Exercise
Find all solutions of the equation in the interval [0, 27).
56 sin? x = 56 – 28 cos x
Step 1
This equation contains both sine and cosine functions. Rewrite the equation using the Pythagorean identity, so
that it has only cosine functions.
56 sin? x = 56 - 28 cos x
56 1 -
= 56 - 28 cos x
= 56 - 28 cos x
