Hi,

NumPy has capabilites for all kinds of trigonometric functions, but still missing out one important bit.
In most every case I know of, both the sine and cosine of an angle need to be computed (e.g. for the representation of a circle).
Numerically, sine and cosine can be evaluated at the same time, thus saving a great deal of complexity. This numerical method is implemented in http://linux.die.net/man/3/sincos, for example.

Cheers,
Nico
