Question 4 (6 points) Listen Describe how to use both an equivalent trigonometric identity and a diagram to demonstrate that two trigonometric ratios are equivalent. a) Use one of the following equivalent trigonometric expressions: sin (0 + 3x = - cos 0 cos (0 -+ 2 - sin 0 tan (0 - 37 2 cot 0 sin 371 2 cos 0 COS 2 - sin 0 tan 2 = cot ! 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 0 and solve both sides to prove that they are equal.)
