key term - Inverse Tangent Function

Definition

The inverse tangent function, also known as arctan or tan^(-1), is an operation that gives the angle whose tangent is a given number. It takes in a ratio of the lengths of two sides of a right triangle and outputs the angle opposite to that ratio.

Cosine Function: The cosine function relates the length of the adjacent side of a right triangle to its hypotenuse. It helps determine angles in trigonometry problems.

Geometric Series:

A geometric series is a sequence of numbers where each term is found by multiplying the previous term by a constant called the common ratio. It has applications in calculus and algebraic equations.

Sine Function: The sine function relates the length of an opposite side of a right triangle to its hypotenuse. It is used extensively in trigonometry and wave analysis.
