Still stressing over manual arctangent calculations? Stuck on trig homework, engineering projects, or data analysis? This arctan calculator is a total game-changer🤩 Input the tan(θ) value, get instant degree and radian results, plus function graphs and common value tables—students/researchers/engineers, dive right in!
📝【2-Step Hack for Beginners!】
- 1. Enter "Value (x)"📥：Input the known tangent value (i.e., result of tan(θ), e.g., 1.0, 0.577, etc.)
- 2. Auto-Calculate：No extra steps needed—instantly get corresponding degrees and radians, done✅
📊【Core Features + Trig Hacks!】
✅ Core Traits
- Dual Unit Output：Displays both degrees (°) and radians (rad) simultaneously.
- Full Domain Support：Works with all real numbers (-∞ to +∞).
- Clear Range Label：Results strictly fall within (-π/2, π/2).
| tan(θ) Value | Corresponding Degrees | Corresponding Radians |
|---|---|---|
| -1.732050808 | -60° | -π/3 |
| -1.000000000 | -45° | -π/4 |
| -0.577350269 | -30° | -π/6 |
| 0 | 0° | 0 |
| 0.577350269 | 30° | π/6 |
| 1.000000000 | 45° | π/4 |
| 1.732050808 | 60° | π/3 |
✅ Key Knowledge
- Definition：Arctan (Inverse Tangent) is the inverse of the tangent function. Input tangent value x, return the corresponding angle θ.
- Notation：Written as y=arctan(x) or y=tan⁻¹(x).
🌰【Real-Life Demo!】
Input x=1.0 → Result: 45° | π/4
Input x=0.57735 → Result: 30° | π/6
Input x=-1.732 → Result: -60° | -π/3
❓【FAQ! Clear All Doubts】
Q：Can I input negative values?
A：Absolutely! Supports positive/negative real numbers.
Q：Why are results only between (-π/2, π/2)?
A：This is the principal value range of arctan，ensuring one unique θ for each x.
⚠️【Common Mistakes to Avoid!】
- Don’t mix up notation：tan⁻¹ is inverse function，not reciprocal (1/tan(x)).
- Follow input format：Enter numbers directly, no units needed.
- Remember the range：Results will never equal ±π/2 (90°/-90°).
