Given the values of sina and sinb , the steps in evaluating the value of sin(a+b) are: Select one: a. Use the compound angles formula for the sum of sines and substitute 1 for cosa and cosb b. Use the Pythagorean identity to find both values of cosa and cosb, then use the compound angles formula for the sum of sines, substitute all the values and calculate c. Add the values of sina and sinb d. Add the values of a and b then use a calculator
