For (x1, y1) and (x2, y2)
If (x1 > x2) then x = x1 - x2 else x = x2 - x1
If (y1 > y2) then y = y1 - y2 else y = y2 - y1
R = Sqrt(x2+y2)
Angle = tan -1(y/x)
Function Description
Cartesian coordinate system-polar coordinate system conversion
Enter the value, click "Calculate" and the result will be displayed.
The rectangular coordinates are (x, y), where x and y are the horizontal and vertical distances from the origin to the point.
The polar coordinates are (R, Q), where R is the distance between the starting point and the point, and Q is the angle between the positive direction of the x-axis and the point.
Calculation formula
Point 1 coordinates (x1, y1), point 2 coordinates (x2, y2)
If x1 > x2, then x = x1 - x2, otherwise if x2 > x1, then x = x2 - x1.
If y1 > y2, then y = y1 - y2, otherwise if y2 > y1, then y = y2 - y1.
R=√(x2+y2)
Angle=tan−1(YX)
Example of use
