Precision: 12 decimals

Formula & Edge Cases

tan(θ) = sin(θ) / cos(θ) = opposite / adjacent

When cos(θ) = 0 (θ = 90° + k·180° or θ = π/2 + k·π), tangent is undefined (approaches ±∞). For numeric stability, the tool treats values where cos ≈ 0 as undefined.

Explanation & Steps

Enter an angle and click Calculate Tan to see step-by-step solution and triangle labels here.

Green wedge shows angle fraction of full circle; triangle shows opposite/adjacent/hypotenuse.

Quick tips

Use degrees for typical geometry problems. Use radians for calculus contexts.
Negative angles rotate clockwise; the triangle diagram will reflect absolute lengths for opposite and adjacent.
If tan is undefined, the triangle will still show sin and cos approximations and flag undefined for tan.

About Wordstoolshub

Wordstoolshub builds lightweight, embeddable web utilities for education and productivity. Our Tangent Calculator demonstrates our approach: no external dependencies, accessible markup, and visual explanations to help learners understand trigonometric relationships like tan(θ) = opposite / adjacent.

Why this tool matters

Interactive visuals improve retention. The triangle diagram links algebraic formulas to geometric intuition so students can see how tangent depends on triangle side ratios. Developers and site owners can embed this single HTML block into WordPress without adding plugins.
