Castrated males are called wethers. Goat meat from younger animals is called kid or cabrito (Spanish), while meat from older animals is known simply as goat or sometimes called chevon, or in some areas mutton (which more often refers to adult sheep meat).
Function Generators. A function generator is a signal source that has the capability of producing different types of waveforms as its output signal. The most common output waveforms are sine-waves, triangular waves, square waves, and sawtooth waves. The frequencies of such waveforms may be adjusted from a fraction of a hertz to several hundred kHz.
Every function which has derivatives of all orders at 0 is the generating function of its Taylor expansion at 0. > 1/(1-x)=series(1/(1-x),x,20); Uses of generating functions. One use for generating functions is get closed formulas for sequences which are defined recursively in terms of previous terms. The defining equations for such sequences are called recurence relations.
