Assessment #3-Unit S Concept 3

• What is the problem about?The problem is about using the power reducing formulas and getting a power of 1. This problem gives sin^4(x) and you will use sin^2(u)= 1-cos(2u)/2 to solve. It also involves using "m" substitution to reach a power of 1.

• What does the viewer need to pay close attention to in order to do the problem correctly?They need to pay attention to using the formula as (1-cos(2x)/2)(1-cos(2x)/2) because we broke down sin^4(x), and how you are supposed to foil the numerators. They should notice that there will be a cos^2(2x). So, using "m" in cos^2(2x) helps us make it a power of 1.
