The full name of cos Theta is cosine of theta.
Cosine is a trigonometric function that relates an angle of a right triangle to the ratio of the length of the adjacent side to the length of the hypotenuse.
Here's a breakdown:
- Cosine: The name of the trigonometric function.
- Theta (θ): A Greek letter commonly used to represent an angle in trigonometry.
Example:
If you have a right triangle with an angle θ, then cos θ would be the ratio of the length of the side adjacent to θ to the length of the hypotenuse.
