Question
Find the value of the given trigonometric
expression: (sin 40°cos 50° + cos²40°) × sin 30° + (cos 60°tan 45°) × sec 60°Solution
(sin 40°cos 50° + cos²40°) × sin 30° + (cos 60°tan 45°) × sec 60° = {sin 40°cos (90° – 40°) + cos²40°} × sin 30° + cos 60°tan 45°sec 60° Using, cos (90° – A) = sin A = (sin²40° + cos²40°) sin 30° + cos 60°tan45°sec 60° Using, sin²A + cos²A = 1 = {1 × (1/2)} + {(1/2) × 1 × 2} = (1/2) + 1 = (3/2)
