âThat meant representation for all.â. Since then, the best of North Carolinaâs legislative leaders, though not all, have presided over its chambers with an eye toward good government. But last weekâs session was a reversion to the strong-arm rule that Republicans decried in the 1980s.
An identity function is a function that always returns the same value as its argument. In other words, the identity function is the function f(x) = x. x.
Thus, cos2(Î¸)+sin2(Î¸)=1. In mathematics an identity is an equality relation A = B, such that A and B contain some variables and A and B produce the same value as each other regardless of what values (usually numbers) are substituted for the variables. In other words, A = B is an identity if A and B define the same functions. This means that an identity is an equality between functions that are differently defined. For example, (a + b)2 = a2 + 2ab + b2 and cos2(x) + sin2(x) = 1 are identities. Identities are sometimes indicated by the triple bar symbol â¡ instead of =, the equals sign.
