Understanding Inverse Trigonometric Functions

Inverse trigonometric functions, commonly known as arcsine, arccosine, and arctangent, are essential concepts in mathematics, particularly in trigonometry. Their utility lies in reversing the relationship of trigonometric functions—finding the angle when given the ratio. This article aims to elucidate the application of inverse trigonometric functions through illustrative examples, making their usage more comprehensible.

Evaluating Inverse Sine

To begin our exploration, let’s evaluate the expression ( \sin^{-1}\left(\frac{1}{2}\right) ). By definition, if we denote the angle as ( \theta ), we have:

[

\sin(\theta) = \frac{1}{2}
