Converted coordinates.Usage Tip
Polar form makes rotation and scaling easy; rectangular form makes adding coordinates easy.
THE MATH
r = √(x² + y²), angle = atan2(y, x)
x = r·cos(angle), y = r·sin(angle)
x = r·cos(angle), y = r·sin(angle)
Rectangular coordinates locate a point by horizontal and vertical distance; polar coordinates use distance and angle.
The two forms describe the same point and convert directly into each other.

Choose the conversion direction.
Rectangular to polar: enter x then y.
Polar to rectangular: enter r then the angle in degrees.
Rectangular to polar: enter x then y.
Polar to rectangular: enter r then the angle in degrees.
