How to use the inverse trigonometric functions calculator
Compute arcsin, arccos and arctan. Enter ratio value in the field above; the arcsin, arccos, arctan are computed instantly and plotted on the chart so you can see how the answer changes.
Formula
Variables
- v — Ratio value
Worked example
With ratio value = 0.5, the calculator gives arcsin ≈ 30 °; arccos ≈ 60 °; arctan ≈ 26.56505 °.
Frequently asked questions
What is the formula for the inverse trigonometric functions calculation?
arcsin (°) = asin(v). arccos (°) = acos(v). arctan (°) = atan(v). Here v is ratio value.
What inputs do I need for the inverse trigonometric functions calculator?
You need ratio value. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use this calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
