cos (sec-1 x) is equal to –
- sin1440° - cot630° - sin120°cos150° is equal to:
sin2 4˚ + sin2 6˚ + sin2 8˚ + sin2 10˚ + ……… + sin2 86˚ =?
Find the value of the given trigonometric expression:
(sin 40°cos 50° + cos²40°) × sin 30° + (cos 60°tan 45°) × sec 60°
...If sec 4A = cosec (3A - 50°), where 4A and 3A are acute angles, find the value of A + 75.
If cosec2A = (sin60o + tan45o X sec245o), then find the value of sin2A.
If cos2B = sin(1.5B + 27 o), then find the measure of 'B'.
Simplify the following trigonometric expression:
10 cos19∘ sec19∘ − 4cot28∘ tan28...
