WebCylindrical Coordinates Transforms The forward and reverse coordinate transformations are != x2+y2 "=arctan y,x ( ) z=z x =!cos" y =!sin" z=z where we formally take advantage of the two argument arctan function to eliminate quadrant confusion. Unit Vectors The unit vectors in the cylindrical coordinate system are functions of position. WebCylindrical coordinates are polar coordinates extended into three-dimensional space by adding the z cartesian coordinate. Thus, cylindrical coordinates can be expressed as cartesian coordinates using the equations given below: x = rcosθ y = rsinθ z = z Cartesian Coordinates to Cylindrical Coordinates
