The value of cos pi can be calculated by constructing an angle of π radians with the x-axis, and then finding the coordinates of the corresponding point (-1, 0) on the unit circle. The value of cos pi is equal to the x-coordinate (-1). ∴ cos pi = -1.
Unit circle and Trigonometry Table Values. In mathematics, a unit circle is a circle with a radius of one. Frequently, especially in trigonometry, the unit circle is the circle of radius one centered at the origin (0, 0) in the Cartesian coordinate system in the Euclidean plane. Using the unit circle, the values of any trigonometric function ...
Trigonometric Tables. (Math | Trig | Tables) PI = 3.141592... (approximately 22/7 = 3.1428) radians = degrees x PI / 180 (deg to rad conversion) degrees = radians x 180 / PI (rad to deg conversion) Those with a zero in the denominator are undefined. They are included solely to demonstrate the pattern.
