はじめに

Inverse Trigonometry Calculator — Compute arcsin, arccos, or arctan of a value. Enter Value, Function to get an instant, accurate result.

計算式

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.

ステップごとの説明

Enter the Value.
Enter the Function.

実例

Example: With Value = 0.5, Function = asin, the Inverse Trigonometry Calculator gives Radians: 0.5236, Degrees: 30.

よくある質問

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.
