Describe how to use both an equivalent trigonometric identity and a diagram to demonstrate that two trigonometric ratios are equivalent. l_l 3} Use one of the following equivalent trigonometric expressions: sin{n9+ 32\") = cos9 (:05 (9+ 37\") = 51119 tan (9+ 32\") = cot9 5111(32? 9) = cos9 cos (% ) = sin9 tan (3; ) = (10139 l_l b) Using a diagram demonstrate how the related angle formulas are true. Create an example to illustrate your findings in part a) [choose a value for 6' and solve both sides to prove that they are equal.)
