Tan Graph (y = tan x) | Interactive Tangent Curve

Tan Graph (y = tan x)

This page shows the tangent graph for y = tan(x). Because tangent has vertical asymptotes (where the graph shoots up/down), this chart highlights asymptotes and safely scales the curve for readability.

Current function: y = 1 · tan(1x)

Key facts: tan(0) = 0, period is π / B (radians) or 180° / B (degrees), and vertical asymptotes occur where cos(x) = 0.

How to read the tan graph

  • The graph crosses the origin: (0, 0).
  • Each “branch” repeats every π (or 180°) when B = 1.
  • Dashed vertical lines show asymptotes where tan(x) is undefined.
  • For readability, very large values are clipped (the true curve goes to ±∞ at asymptotes).
