Question

What is the distance formula? in trigonometry

Answer 1

In trigonometry the distance formula is used to find the distance between any two points.

The formula is given by

`d=√((x_2-x_2)^2+(y_2-y_1)^2)`

Explanation:

Distance formula is used to find the distance between two points.

Let us suppose, there are two points A and B in xy- plane whose coordinates are

`A(x_1,y_1),B(x_2,y_2)`

If d is the distance between these two points then the distance between A and B can be find using the below formula

`d=√((x_2-x_2)^2+(y_2-y_1)^2)`
