Inverse Trigonometric Functions Calculator
Calculate arcsine, arccosine, and arctangent to find angles from ratios
About this calculator
The Inverse Trigonometric Functions Calculator helps you find angles when you know trigonometric ratios. By inputting values for sine, cosine, or tangent ratios, this calculator computes the corresponding angles using arcsine (sin⁻¹), arccosine (cos⁻¹), and arctangent (tan⁻¹) functions. This tool is essential for students, engineers, and professionals working with triangles, waves, rotations, and periodic phenomena where determining angles from known ratios is crucial for solving complex mathematical and real-world problems.
How to use
Enter the trigonometric ratio value (between -1 and 1 for arcsine and arccosine, any real number for arctangent) into the appropriate input field. Select your preferred angle unit (degrees or radians). Click calculate to instantly get the corresponding angle value using the inverse trigonometric function.
Frequently asked questions
