High-Precision Tangent Calculator
Calculate the tangent of any angle with adjustable precision from 1 to 1000 decimal places. Supports degrees and radians, shows step-by-step solutions, and clearly flags vertical asymptotes (e.g., 90° + k·180°).
About High-Precision Tangent Calculator
Welcome to the High-Precision Tangent (tan) Calculator. This tool delivers ultra-accurate tangent values with user-selectable precision from 1 to 1000 decimal places. Enter an angle in degrees or radians, see a step-by-step solution, and get clear warnings when the input is at a vertical asymptote (e.g., 90°, 270°, …).
Why use a high-precision tangent calculator?
- Arbitrary precision: Go well beyond typical 15–16 digit limits.
- Degrees or radians: Flexible input modes.
- Asymptote awareness: Detects undefined points at 90° + k·180° (π/2 + k·π).
- Educational output: Normalization (period π), unit circle coordinates, and exact values at special angles.
- Visualization: See the unit circle point and a line whose slope equals tan(θ).
- Research-ready: Backed by mpmath for reliable arbitrary-precision math.
Understanding tangent
The tangent of an angle θ is defined as tan(θ) = sin(θ)/cos(θ). Tangent is periodic with π (180°). It is undefined when cos(θ) = 0, which occurs at odd multiples of π/2 (90°, 270°, …). Near those angles, tan(θ) grows without bound in magnitude.
