Homogeneity formula

Web7 jan. 2024 · The General Solution of a Homogeneous Linear Second Order Equation If y1 and y2 are defined on an interval (a, b) and c1 and c2 are constants, then y = c1y1 + c2y2 is a linear combination of y1 and y2. For example, y = 2cosx + 7sinx is a linear combination of y1 = cosx and y2 = sinx, with c1 = 2 and c2 = 7. In mathematics, a homogeneous function is a function of several variables such that, if all its arguments are multiplied by a scalar, then its value is multiplied by some power of this scalar, called the degree of homogeneity, or simply the degree; that is, if k is an integer, a function f of n variables is homogeneous of degree k if for every and
