The arctan derivative refers to the rate of change of the inverse tangent function. It represents how the output of the arctan function changes with respect to its input.
The tangent function relates the ratio of two sides of a right triangle. It gives us the slope or steepness of a line passing through a point on the unit circle.
The chain rule is used when finding derivatives of composite functions. It helps us calculate how changes in one variable affect another variable within a function.
