Arctan Calculator

Calculate inverse tangent (arctan) values in degrees and radians with MaiCalcs. Works with all real numbers and provides precise results.

Arctan Calculation

Arctan Properties:

• Domain: All real numbers (-∞, ∞)

• Range: (-π/2, π/2) or (-90°, 90°)

• arctan(-x) = -arctan(x)

• arctan(tan(x)) = x for x ∈ (-π/2, π/2)

Common Values:

• arctan(-∞) = -90° = -π/2 rad

• arctan(-√3) = -60° = -π/3 rad

• arctan(-1) = -45° = -π/4 rad

• arctan(-1/√3) = -30° = -π/6 rad

• arctan(0) = 0° = 0 rad

• arctan(1/√3) = 30° = π/6 rad

• arctan(1) = 45° = π/4 rad

• arctan(√3) = 60° = π/3 rad

• arctan(∞) = 90° = π/2 rad
