text: A vector from the origin (zero) is rotated in a series of "n" small steps δΘ so that the sum of all the steps is equal to Θ. By accumulating the corresponding changes in the values of its orthogonal coordinates δX and δY at each step, the values of X and Y and hence the tangent can be calculated.
