If (2sin A + cos A) = 3sin A, then find the value of cot A.
If tan 4Īø = cot 14Īø, then find the value of cos 9Īø.
If sin A = 3/5 and cos B = 4/5, where A and B are acute angles, find the value of sin(A + B).

If tan Īø + cot Īø = 2 where 0 < Īø < 90 ; find the value of tan30 Īø + cotĀ 29Ā Īø.
- If sin (3A ā 4B) = (1/2) and cos (A + B) = (ā2/2), where 0° < A, B < 90°, then find the value of āAā.
If Īø is an acute angle and sin Īø + cosec Īø = 2, then the value of sin2 Īø + cosec2 Īø is:
