Cos pi radians in degrees is written as cos ( (π) × 180°/π), i.e., cos (180°). In this article, we will discuss the methods to find the value of cos pi with examples. What is the Value of Cos pi? The value of cos pi is -1. Cos pi can also be expressed using the equivalent of the given angle (pi) in degrees (180°). Explanation:

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cosine is negative in the second quadrant. The exact value of cos(0) cos (0) is 1 1. Multiply −1 - 1 by 1 1.

What is the value of sin π and cos π? Solution: In a right angle triangle, sin (θ) is the ratio of the opposite (perpendicular) side to the hypotenuse, while cos (θ) is the ratio of the base (adjacent) side to the hypotenuse. π = 180º and π/2 = 90º. Using trigonometric identity, sin θ = cos (90º - θ) and cos θ = sin (90º - θ)
