Cos 50 Cos 40 Sin 50 Sin 40

Cos 50 Cos 40 Sin 50 Sin 40. You can put this solution on YOUR website! Please simplify each trigonometric expression 1 sin (40 ) cos (50 )+cos (40 ) sin (50 ) = sin (40+50) = sin 90 = 1 ==================== 2 cos 105 cos 15 sin 105 sin 15 .

We’ll get sin 40°×1/cos 50°+cos 40°×1/sin50° or sin40÷cos 50+cos40÷sin 50————1 We know that sinA and cosA are complementary angles thus cos 40 can be written as sin 50 and similarly sin 50 can be written as cos 40 Put these values in 1 We’ll get sin40÷sin40+cos40÷cos 40 or 1 + 1 which’ll give 2 Thus answer is 2.
