Question

if alpha = 90° and beta = 30°then the value of sin ( alpha - beta) is?​

Answer 1

Answer:

1/2

Step-by-step explanation:

Hope it helps not so much sure about the ans

Answer 2

If α + β = 90°, then maximum value of sin α sin β is. The range of sin 2α is [-1, 1] since the range of sin x is [-1, 1]. Hence, the maximum value of (1/2) sin 2α or is sin α sin β is 1/2.
