- Click ‘Calculate’.
- View the result and chart below.
Formula & Methodology
The formula for tangent inverse is: arctan(x) = θ, where x = tan(θ). Our calculator uses the Math.atan() function in JavaScript, which is based on the arctangent function.
Real-World Examples
Example 1: Angle of a Ramp
If a ramp has a tangent of 0.5, what’s the angle?
tan^-1(0.5) = 26.565°
Example 2: Inclination Angle of a Slope
If a slope has a tangent of 1.2, what’s the angle?
tan^-1(1.2) = 50.198°
Example 3: Angle of a Roof
If a roof has a tangent of 0.8, what’s the angle?
tan^-1(0.8) = 38.69°
