Cg provides a set of built-in functions and structures to simplify GPU programming. These functions are similar in spirit to the C standard library functions, providing a convenient set of common functions. The Cg Standard Library functions are documented in the Cg Standard Library index. Vertex Program Profiles A few features of the Cg language that are specific to vertex program profiles are required to be implemented in the same manner for all vertex program profiles.
The idea is the same in trigonometry. Inverse trig functions do the opposite of the âregularâ trig functions. Inverse sine (sinâ1)(\sin^{-1})(sinââ1ââ)left parenthesis, sine, start superscript, minus, 1, end superscript, right parenthesis does the opposite of the sine.
