Equally as important as sin(x) and cos(x) is atan2(y,x). Just as sin and cos
are useful for converting polar coordinates to rectangular coordinates, atan2
is essential for converting rectangular coordinates to polar.
With atan2 and sqrt, computing other inverse trigonometric functions is easy,
just as it is easy to compute tan given implementations for sin and cos.
