how to graph trig functions

Graphing the Basic Equations. Draw a coordinate plane. For a sine or cosine graph, simply go from 0 to 2π on the x-axis, and -1 to 1 on the y-axis, intersecting at the origin (0, 0). repeat the same shape from negative infinity to positive infinity on the x-axis (you’ll generally only graph a portion of it).

Is Desmos radians or degrees?

Desmos can operation in radians or degrees, this is set from the coordinates dialog box available via the monkey wrench icon. Desmos also has a scientific calculator that can be set in degrees or radians. This is a scientific calculator on the same steroids as Desmos’ graphing calculator.

What does a sine graph look like?

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 +1 to -1. Curves that follow this shape are called ‘sinusoidal’ after the name of the sine function.
