What is the value of TAN 22 and half degree?

Answer: The value of tan 22.5 degree is √2 – 1.

How do you solve cos 22?

The value of cos 22 degrees can be calculated by constructing an angle of 22° with the x-axis, and then finding the coordinates of the corresponding point (0.9272, 0.3746) on the unit circle. The value of cos 22° is equal to the x-coordinate (0.9272). ∴ cos 22° = 0.9272.

How do you find sin 40?

The value of sin 40 degrees is 0.6427876. . .. Sin 40 degrees in radians is written as sin (40° × π/180°), i.e., sin (2π/9) or sin (0.698131. . .)….We can use trigonometric identities to represent sin 40° as,

  1. sin(180° – 40°) = sin 140°
  2. -sin(180° + 40°) = -sin 220°
  3. cos(90° – 40°) = cos 50°
  4. -cos(90° + 40°) = -cos 130°
