Question
The Earth rotates on its axis from ____ to
____.Solution
The Earth rotates from west to east, which is why the Sun appears to rise in the east and set in the west. This rotation is responsible for the day and night cycle experienced globally.
If cos2B = sin(1.5B + 27 o), then find the measure of 'B'.Â
If sec a + tan a = 3, find the value of sin a.Â
If tan 4θ = cot 14θ, then find the value of cos 9θ.
If sec 4A = cosec (3A - 50°), where 4A and 3A are acute angles, find the value of A + 75.
The maximum value of 45 sin θ + 28 cos θ is:
- Find the value of sin²10° + sin²80° + cos²15° + cos²75°.

- If sin (2A − 3B) = (1/2) and cos (A + B) = (√3/2), where 0° < A, B < 90°, then find the value of ‘A’.
Simplify the following trigonometric expression:Â
15 cos 25° cosec 65° − 5 cot 80° cot 10°
