Question

solve the following trigonometric equations when I greater equal than theta and geeta equal than 90​

Answer 1

Answer:

1st one cos theta =root 3/ (2)

so theta is equal to 30 degrees

sin2 theta is equal to 1/root 2 so 2 theta is equal to 45 and finally theta is equal to 27.5

and finally cot 5 theta is equal to 1, so theta 45 degrees so theta is 45/5 and that is equal to 9
