How to Graph the Sine Function?

The sine of an angle is a trigonometric function denoted by \(sin x\) where \(x\) is the desired angle. In this guide, you will learn more about the graph of the sine function.

How to Graph the Sine Function?

A step-by-step guide to graphing the sine function

The sine function is one of the three main functions in trigonometry. The sine \(x\) or sine theta can be defined as the ratio of the opposite side of a right triangle to its hypotenuse.


The sine graph is like the picture below. A sine graph or sinusoidal graph is an up-down graph and repeats every \(360\) degree, i.e. in \(2π\). In the graph below, it can be seen that from \(0\), the sine graph increases to \(+1\) and then decreases to \(-1\) from where it increases again.

The function \(y = sin x\) is an odd function, because; \(sin (-x) = -sin x\).
