Distance calculator between two points
Commonly used in application problems to find the distance in a function graph and then find the coordinates of a point through the distance.
Given that the coordinates of points A and B are A(x1,y1) and B(x2,y2) respectively
The square of the distance AB between the two points is
AB²=(x1-x2)²+(y1-y2)²
After calculating, take the square root to get the distance AB.
For example: Given that the coordinates of points A and B are A(1,2) and B(4,6) respectively
AB²=(1-4)²+(2-6)²=25
AB=√25=5
You can also calculate directly:
AB=√[(1-4)²+(2-6)²]=√25=5
