How to Write the Equation of a Sine Graph
On this page: Read the parameters · Worked graph example · Check your equation To write a sine equation from a graph, find the midline, amplitude, period, and a midline crossing. Use \(y=A\sin(B(x-h))+D\), where the amplitude is \(|A|\), the period is \(P=2\pi/|B|\), the horizontal shift is \(h\), and the midline is \(y=D\). The parameter \(B\) […]
How to Graph the Sine Function?
The sine function graphs as a wave that repeats every 2 pi, oscillating between 1 and negative 1. Its amplitude, period, phase shift, and vertical shift each map to one part of the equation. In this lesson Graph the Sine Function: what to notice and how to work it What to notice first Common student […]
