# The new math.. er--trig

A friend of mine just pointed out DIVINE PROPORTIONS: Rational Trigonometry to Universal Geometry. Having had to refresh my Trig understanding for a number of recent projects (basically any time graphics are involved), I like the concept of getting rid of sin, cos, etc. in favor of simpler rational math.

But what's even more interesting about *Divine Proportions* are its implications for graphics processing. Being able to get rid Trig functions in 3D calculations and replace them with simple squares and fractions should allow some significant speed increases in processing. Curious how this plays out.
