For example, some trigonometric identities or formulas that are helpful when dealing with finding trigonometric functions of large angles are as follows: $$\begin{align*} \sin \left( {360 + \theta } \right) &= \sin \left( \theta \right)\\ \cos \left( {360 + \theta } \right) &=...
Doing the calculation, you see that the period for the function is pi over 2, or 1.57. Usually, when working with trig functions, you'll leave the pi as is and simplify the rest. So your answer will be pi over 2 instead of the 1.57. Example Lesson Summary Additional Activities Fi...
