Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more.

It starts at 0, heads up to 1 by π /2 radians (90°) and then heads down to −1. Cosine is just like Sine, but it starts at 1 and heads down until π radians (180°) and then heads up again. In fact Sine and Cosine …

Oct 20, 2025 · In this tutorial, we explore how to draw the graph of sin x, its shape, key characteristics, and how it compares to cosine and sine graphs commonly seen in trigonometry.

Jul 23, 2025 · The purpose of this article is to include a discussion of the properties of sine and cosine functions and detailed guidance on how best to graph such functions, including a discussion of …

To graph the sine function, we mark the angle along the horizontal x axis, and for each angle, we put the sine of that angle on the vertical y-axis. The result, as seen above, is a smooth curve that varies from …

Here we will learn about sine graphs, including how to recognise the graph of the sine function, sketch the sine curve and label important values, and interpret the sine graph.

We have created the graphs of the sine and cosine functions by following a point from the positive x axis one complete rotation counterclockwise around the unit circle.
