question 3.

Question 4 (6 points) 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+ 2) = - cos cos (0 + 2 = sin 0 tan (0 + 37 2 = - cot 0 sin 2 = - cos 0 COS 371 2 = - sin 0 tan 2 0) = cot 0 (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.)Prove the following identities: (If it is a one step problem please state the formula used) Ob) sec (3,!) cos (y) = 1311(9) 5111(9) C] C) 1 1 2 1sin(z) + 1+sin{$} = 253 (5\") Dd) tan (3:) + tan (y) = smy) coals) cos(y) C] e) sin (:3) tan (3) = mm col:2 (3)
