Interactive Trig Graph

Explore how amplitude and phase shift affect the sine graph

Controls

Current function:

y = 1.0 sin(x + 0.0)

How it works

The graph shows the function:

y = A sin(x + φ)

  • Amplitude A makes the graph taller or shorter.
  • Phase φ shifts the graph left or right.
  • Zoom lets you see more or fewer cycles.

Graph of y = A sin(x + φ)
