What is this about?
A problem is presented from Unit S concept, which is solving equations with half-angle formulas. This problem goes over solving an a trig equation that contains a half-angle using the half-angle formulas learned in this unit. Knowledge from previous units are needed to solve this problem. Things such as the unit circle values, identities, and extraneous solutions will be dealt with in this problem.
What does the viewer need to pay special attention to in order to understand the concept?
-The viewer need to pay close attention to is to the identities being used in this problem especially the ones reviewed from unit Q and how they are being substituted in.
- The second thing to keep in mind is that at the beginning of the problem we squared the equation and since we raised the problem it is very important to go back and check for any extraneous solutions.
