Inverse Tangent Function Concepts

This video tutorial covers the evaluation of inverse tangent functions, focusing on understanding the range and domain of the inverse tangent function. It provides step-by-step examples of evaluating inverse tangent for specific values, such as 1, 0, and the square root of three. The tutorial emphasizes the importance of knowing the unit circle and the range of the inverse tangent function to correctly evaluate these functions. It concludes by discussing the domain of the inverse tangent function, which includes all real numbers, and highlights that any real number can be used as input for the inverse tangent function.
