This paper presents an algorithm for computing Sine-Cosine pairs to modest
accuracy, but in a manner which contains no conditional tests or branching,
making it highly amenable to vectorization. An exemplary implementation for
PowerPC AltiVec processors is included, but the algorithm should be easily
portable to other achitectures, such as Intel SSE.
