Computes both sine and cosine of x at the same time.
Remember to link the math library: valac -X -lm ...
Several applications need sine and cosine of the same angle x. This function computes both at the same time, and stores the
results via the output variables.
| x |
A numeric value in radians. |
| sinx |
Output variable for sine of |
| cosx |
Output variable for cosine of |
