 Solving Using Sum/Difference Formulas------------------------>

Solving Using Half Angle Formula             
<---------------










These two ways of finding the values of the trig functions give the same answers they are both simplifying through radical other formulas, just in a different process. The multiples within the trig functions are similar, and when you plug each of them in the calculator, they will give the same answers for each of them. Also, since we are using the half angle within the sum/difference formula, it is similar to using the "u" , but taking the square root of the values. Therefore, since each values come out the same, in know that there are two ways of finding the values of these trig function and angles.
