👉 In mathematics, a bilinear form is a function that takes two vectors and returns a scalar. This means it can be used to measure how much each vector in a space differs from another vector. For example, if we have a vector space over some field F, a bilinear form would take the vector (x, y) as input and return a scalar z such that: z = x^2 + y^2 This function can be used to measure how much each vector in the
