Usually, cylindrical coordinates refers to the transformation
x = r cos(theta),
y = r sin(theta),
z = z,
although x, y, and z can be permuted. Cylindrical coordinates (r, theta, z) are very useful for describing three-dimensional objects whose cross-sections are easy to express in polar coordinates. Circular cylinders are a good example.
