Introduction
Inverse Trigonometry Calculator — Compute arcsin, arccos, or arctan of a value. Enter Value, Function to get an instant, accurate result.
Formula
Computes arcsin, arccos, or arctan of a value in radians, then converts the result to degrees. arcsin and arccos require the input to be between −1 and 1.
Step-by-step
- Enter the Value.
- Enter the Function.
- Click Calculate to see your result instantly.
Real-world example
Example: With Value = 0.5, Function = asin, the Inverse Trigonometry Calculator gives Radians: 0.5236, Degrees: 30.
Frequently Asked Questions
What if I enter a value outside −1 to 1 for arcsin or arccos?
Those functions are only defined on that range, so no result is returned.
Is the result in degrees or radians?
Both are shown, but degrees is the primary result.
What inputs does the Inverse Trigonometry Calculator need?
You'll need to provide: Value, Function. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Inverse Trigonometry Calculator?
The Inverse Trigonometry Calculator applies the formula exactly as calculated — Computes arcsin, arccos, or arctan of a value in radians, then converts the result to degrees. arcsin and arccos require the input to be between −1 and 1. — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Inverse Trigonometry Calculator free to use?
Yes, the Inverse Trigonometry Calculator is completely free, requires no signup, and runs instantly in your browser.
About the Inverse Trigonometry Calculator
The Inverse Trigonometry Calculator uses a real, verifiable formula — Computes arcsin, arccos, or arctan of a value in radians, then converts the result to degrees. arcsin and arccos require the input to be between −1 and 1. — so results are accurate every time, not an approximation.
