The Inverse Trigonometric Calculator is a useful online tool that helps you find the angles corresponding to given trigonometric ratios. It supports three main inverse trigonometric functions — asin (inverse sine), acos (inverse cosine), and atan (inverse tangent). Simply enter a numeric value, select the desired function, and choose whether you want the answer in radians or degrees. The calculator automatically validates input values to ensure they fall within the correct mathematical domain and instantly displays accurate results. This tool is ideal for students, teachers, and professionals who work with geometry, trigonometry, or physics, and it can be easily embedded into any website or WordPress page using a simple HTML block.
