Inverse Trigonometric Calculator
🔢 Inverse Trigonometric Calculator – Instantly Find sin⁻¹, cos⁻¹, tan⁻¹ Values
Looking for a quick way to calculate inverse trigonometric functions like arcsin, arccos, or arctan? You’re in the right place! Our free Inverse Trigonometric Calculator lets you compute sin⁻¹, cos⁻¹, and tan⁻¹ in degrees with just one click.
Whether you’re a math student, engineer, or curious learner, this calculator will make your trigonometry work faster and easier.
🎯 What Are Inverse Trigonometric Functions?
Inverse trigonometric functions do the reverse of sine, cosine, and tangent. They help you find angles when you already know the ratio.
- Arcsin (sin⁻¹) gives the angle when the sine is known.
- Arccos (cos⁻¹) gives the angle when the cosine is known.
- Arctan (tan⁻¹) gives the angle when the tangent is known.
These functions return values in degrees and are vital in geometry, calculus, physics, and engineering.
⚙️ How to Use the Inverse Trigonometric Calculator
Using this calculator is simple and intuitive:
- Enter a numeric value (e.g.,
0.5,1, or-0.75). - Select the function – Arcsin, Arccos, or Arctan.
- Click the “Calculate” button.
- Instantly view the angle in degrees.
✅ Supports real numbers
✅ Results are accurate up to 6 decimal places
✅ Works on both mobile and desktop
📚 Formula Behind the Scenes
This tool uses the JavaScript Math library to compute:
- sin⁻¹(x) =
Math.asin(x) - cos⁻¹(x) =
Math.acos(x) - tan⁻¹(x) =
Math.atan(x)
Then, it converts the result from radians to degrees using this formula: degrees=radians×(180/π)degrees = radians × (180 / π) degrees=radians×(180/π)
🧠 Examples of Inverse Trig Calculations
| Function | Input | Output (in Degrees) |
