For example, let a set consist of vectors u, v, and w.Also let k and l be real numbers, and consider the defined operations of and. Range The range is all possible values to get out of the function. In linear algebra, a set of elements is termed a vector space when particular requirements are met. So, if w is a fixed number and q is any angle we have the following periods. Period The period of a function is the number, T, such that f (q + T ) = f (q ). ![]() Q can be any angle q can be any angle 1ö æ q ¹ ç n + ÷ p, n = 0, ± 1, ± 2, K 2ø è q ¹ n p, n = 0, ± 1, ± 2, K Y sin q = y 1 x cos q = x 1 y tan q = xįacts and Properties Domain The domain is all the values of q that can be plugged into the function.
