please help!!

Thanking you in advance:)

Question 1 and 2

D 3) Find all solutions for 5111(33) = g C] b) If 51n(:1:) = % and sec(y) = E, where U E :12 E g and U i: y E % , evaluate the expression sin (a: y). Question 2 (6 points) Solve for all values ofx in the given intervals: Stan (m)+ 11 = 19 for a) O 033: E 211' C] b) sec2 (1:) = 21;.31'12 (:3) for at: E R C] C) see2 (as) + sec2 (:3) 1 = 3 for are R Prove the following identities: (If it is a one step problem please state the formula used) [ a) COS ( -x = sin (x) sec (y) - cos (y) = tan (y) sin (y) 1 1 1-sin(x) + 1+ sin(x) = 2 sec- (x) O d) tan (x) + tan (y) = sin(cty) cos () cos(y) sin (x ) tan (x) = cos () cot (x)Question 4 (0 points} Describe how to use both an equivalent trigonometric identity and a diagram to demonstrate that two trigonometric ratios are equivalent. C] a} Use one of the following equivalent trigonometric expressions: sin (3+ %) cos' cos (9+ 33\") : sine tan (9+ 37'\") = cot9 si11(32Tr 9) = cost9 cos (3?" 6') : sin0 1:31.110?"r 9) = c0136 O b) Using a diagram demonstrate how the related angle formulas are true. Create an example to illustrate your ndings in part a) (choose a value for I9 and solve both sides to prove that they are equal.)
