Student Video #4: Unit S. Concept 3 - #5

• What is this video about? 

     This trigonometric video lesson goes over how to solve problems by using the     power-reducing formulas.

• What does the viewer need to pay special attention to in order to understand the concept?    

      Please understand that we substitute the power-reducing formula to the entire given trig function, not just the (x). Moreover, note that for your final answer, you want the highest power to be 1.

***DISCLAIMER: These problems look a lot scarier than they are. With practice, they become super fast, easy, and even fun! :D
