If we the value of sin 15 degrees then we can easily evaluate the value of cos 15 degrees by using trigonometry identity sin2 a + cos2 a = 1 Put a = 15° Sin215° + cos2 15° = 1 Since Sin 15° = (√3–1)/2√2 [ (√3–1)/2√2]2 + cos215 = 1 On solving the above equation we get Cos 15° = √3+1/2√2.

What is the value of sin 15 °cos15°? Quora

cos 15° – sin 15° = cos(90° – 75°) – sin 15° = sin 75° – sin 15° Using the formula sin x – sin y = 2 cos(x + y)/2 sin(x – y)/2 = 2 cos(75° + 15°)/2 sin(75° – 15°)/2 = 2 cos 45° sin 30° = 2 (1/√2) (1/2) = 1/√2.
