Interactive Trig Graph

Explore y = a·f(bx + c) + d

Controls

Function
Sine
Cosine
Tangent

Amplitude (a) Frequency (b) Phase shift (c) Vertical shift (d) Horizontal zoom

Current function:

y = 1.0 sin(1.0x + 0.0) + 0.0

How each parameter affects the graph

a — amplitude (height of peaks/troughs)
b — frequency (number of cycles)
c — horizontal phase shift
d — vertical shift
Mode — choose sine, cosine, or tangent
