Why Is Cos0 Equal To 1? [Solved]

cos(0) = 1 As this angle gets smaller, the lengths of the hypotenuse and side adjacent to the angle get closer and closer. Once the angle measurement hits 0, the hypotenuse and the adjacent side will lie perfectly on top of each other, falling into a 1-to-1 ratio. Thus, the cosine of 0 is equal to 1.

Why is cosθ decreasing ? cos0° = 1 ; cos90° = 0 | JEE Basics

Trigonometric values of ratios like sinθ, cosθ, tanθ etc. have different values at different angles such as 0°, 30°, 45°, 60°, and 90° .
