What is the value of sin 22 and half?

Answer: The exact value of sin 22.5° using the half-angle formula is √(2 – √2) / 2 or 0.38. Let us proceed step by step to find the exact values of sin 22.5° using the half-angle formula. If θ = 22.5° then 2θ is 45°.

How do you find the value of cos 27?

The value of cos 27° is equal to the x-coordinate (0.891). ∴ cos 27° = 0.891.

How do you find the value of tan 27?

For tan 27 degrees, the angle 27° lies between 0° and 90° (First Quadrant). Since tangent function is positive in the first quadrant, thus tan 27° value = 0.5095254. . . Since the tangent function is a periodic function, we can represent tan 27° as, tan 27 degrees = tan(27° + n × 180°), n ∈ Z.

How do you find the value of sin 36?

The value of sin 36° is equal to the y-coordinate (0.5878). ∴ sin 36° = 0.5878.
