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.
5. You can find t d using the graph of the exponential function. To do this, graph the exponential function and the horizontal line corresponding to twice the original population. The first coordinate of the intersection point will give you the time when the initial population doubles. It has to be t d.
