Simplify: sin (A + B) sin (A - B)
If cos2B = sin(1.5B + 27 o), then find the measure of 'B'.Ā
If tanĪø ā cotĪø = a and cosĪø + sinĪø = b, then (b2 ā1)(a2 + 4) = ?
If cosec (2A + B) = 1 and cosec (A + B) = (2/ā3), find the value of (4A ā B).
Evaluate the following:
sin 60° à cos 30° + sin 30° à cos 60°
The minimum value of 12 sin Īø + 5 cosĪø is
- If sec A = 2, then what will be the value of sin² A?
- If cos2B = sin(1.5B - 36 o ) , then find the measure of 'B'.
