So this expression up here is also equal to 0. Or another way to view it is that if g is a solution to this second order linear homogeneous differential equation, then some constant times g is also a solution. So this is also a solution to the differential equation.

WebAny homogeneous linear differential equation–of any order whatsoever—with constant coefﬁcients has at least one solution of the form y = e t for a suitable choice of . In solving the equation, we will therefore simply have to ﬁnd what has to be. It turns out that this reduces to a simple problem in algebra. WebNorm of a vector. The norm is a function, defined on a vector space, that associates to each vector a measure of its length. In abstract vector spaces, it generalizes the notion of length of a vector in Euclidean spaces. There is a tight connection between norms and inner products, as every inner product can be used to induce a norm on its space.
