Question
Bioactive component present in clove which gives strong
and pungent odourSolution
Eugenol  is the main bioactive compound of clove.
Find the value of the given trigonometric expression:
(sin 15°cos 75° + cos²15°) × sin 30° + (cos 60°tan 45°) × sec 60°
...Find the maximum value of 20 sin A + 9 cos A.
If cos1.5B = sin(B + 5°), then find the measure of 'B'.
- If sec A = 2, then what will be the value of sin² A?
If tanθ = 3/4 and θ is acute, find sinθ and cosθ, and verify that sin²θ + cos²θ = 1.
- If 2cosec 2  A – cot 2 A = 5 and 0 o < A < 90 o , then find the value of ‘A’.
If sinθ = 5/13 for an acute angle θ, find:
(a) cosθ, (b) tan(90° − θ).
- If (tan 4x · tan x = 1), then find the value of (tan 5x).
If tan 3.5θ x tan 6.5θ = 1 then the value of tan 5θ is
