How do you find the value of cos180?

The value of cos 180 degrees can be calculated by constructing an angle of 180° with the x-axis, and then finding the coordinates of the corresponding point (-1, 0) on the unit circle. The value of cos 180° is equal to the x-coordinate (-1). ∴ cos 180° = -1.

How do you calculate cos180?

The value of cos 180 degrees is -1. Cos 180 degrees in radians is written as cos (180° × π/180°), i.e., cos (π) or cos (3.141592. . .)….We can use trigonometric identities to represent cos 180° as,

  1. -cos(180° – 180°) = -cos 0°
  2. -cos(180° + 180°) = -cos 360°
  3. sin(90° + 180°) = sin 270°
  4. sin(90° – 180°) = sin(-90°)

How do you find sin 135?

The value of sin 135 degrees can be calculated by constructing an angle of 135° with the x-axis, and then finding the coordinates of the corresponding point (-0.7071, 0.7071) on the unit circle. The value of sin 135° is equal to the y-coordinate (0.7071). ∴ sin 135° = 0.7071.

How do you solve sin 150?

How to Find the Value of Sin 150 Degrees?
