Make Pictures Fun & Games Geek Stuff. This little program converts your picture to ASCII text art-a jumble of letters, numbers and symbols that do not appear to have any significance until you step back and look at the whole picture. It has no practical purpose, other than the neat factor. ASCII Art has a long history among geeks.
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.
Defining relations for tangent, cotangent, secant, and cosecant in terms of sine and cosine. The Pythagorean formula for sines and cosines. This is probably the most important trig identity. Identities expressing trig functions in terms of their complements. There's not much to these. Each of the six trig functions is equal to its co-function evaluated at the complementary angle. Periodicity of trig functions. Sine, cosine, secant, and cosecant have period 2 Ï while tangent and cotangent have period Ï. Identities for negative angles. Sine, tangent, cotangent, and cosecant are odd functions while cosine and secant are even functions.
