The exact value of sin 180 is zero. Sine is one of the primary trigonometric functions which helps in determining the angle or sides of a right-angled triangle. It is also called trigonometric ratio. If theta is an angle, then sine theta is equal to the ratio of perpendicular and hypotenuse of the right triangle.

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.

What is the value of sin and cos 180?
