Graphs of Trigonometric Functions

Sine, Cosine and tangent are the three important trigonometry ratios, based on which functions are defined. Below are the graphs of the three trigonometry functions sin x, cos x, and tan x. In these trigonometry graphs, x-axis values of the angles are in radians, and on the y-axis, its f(x) is taken, the value of the function at each given angle.

Sin Graph

• y = sin x
• The roots or zeros of y = sin x is at the multiples of π
• The sin graph passes the x-axis as sin x = 0 there
• Period of the sine function is 2π
• The height of the curve at each point is equal to the line value of sine
