 cot 14˚  ...If (sin A + cos A) = √3 cos (90° - A), then find the value of cot A.
- If 2cos²A + 3sin²A = 13/5, then find the value of (sec²A - 1)
If sin (2x + 50) o = cos (2y - 50) o, such that, 0o < x + y < 90o, then find the value of tan(x + y) .
- If sin(A + B) = √3/2 and cos(A + 2B) = 0, where 0° < A, B < 90°, then find the value of tan(2A).
If cos 2A = 1, then find cos A
