Graphs of Trigonometric Functions

To each angle x, there corresponds a unique value for the trigonometric ratios and hence the trigonometric ratios such as sinx, cosx, tanx including the reciprocal ratios are the functions of the angle x.

A function can be represented in various ways. One of the important ways by which a function can be represented is the graph. In a trigonometric function, the variable is the angle. For different values of the angle, the values of the trigonometric ratios will be different.

 

To draw the graph of a trigonometric function, we take the angle x along the X-axis and the value of trigonometric ratio sinx, cosx, tanx, etc. along the Y-axis. Taking different values of the angle as the x-coordinates, and the corresponding values of the trigonometric ratio as y-coordinates, we plot the points (x, sinx), etc. on the plane with rectangular axes. Then we join these points freely to get the required graph of the trigonometric function.

Pie Chart

A pie chart is a circular graph in which the angles of the different sectors represent the corresponding frequencies of different data.

Line Graph

We can represent the data in a line graph in which the frequencies are along the y-axis and the variables are along the x-axis. We can choose a suitable scale so that the entire data is accommodated in the space available.

The line graph is used to show the changes and the relationship between quantities.

Bar Graph

A bar graph is a pictorial representation of data in which bars of uniform width are drawn with equal spacing between them on one x-axis depicting the variable. The value of the variable are shown on the y-axis, and the heights of the bars depend on the values of the variable.
