# How to Graph Trigonometric Functions?

We can plot diagrams of different trigonometric functions with a range of their principal values. Learn how to plot diagrams of trigonometric functions by the following step-by-step guide.

Trigonometric functions are the basic six functions that have a domain input value as an angle of a right triangle, and a numeric answer as the range. The trigonometric function is also called the trig function.

## A step-by-step guide to trigonometric functions graph

Graphs of trigonometric functions have the domain value of $$θ$$ shown on the horizontal $$x$$-axis and the range value along the vertical $$y$$-axis. The graphs of $$sin\:\theta$$ and $$tan\:\theta$$ pass through the origin and the graphs of other trigonometric functions do not pass through the origin. The range of $$sin\:\theta$$ and $$cos\:\theta$$ is limited to $$[-1, 1]$$. The range of infinite values is presented as drawn beside the dotted lines.
