How to Find Cosine Value?
The cosine function is defined as the ratio of the length of the base to that of the length of the hypotenuse in a right-angled triangle. The sign is a trigonometric function of an angle. It is denoted as cosθ, where θ is the angle between the two sides.
Find the cosine value if the θ = 60°
Given θ = 60°
cos60° = 1 / 2
Similarly, you can try the calculator to find the cosine values for the following:
- θ = 30°
- θ = 150°
