How to prove Cauchy-Schwarz integral inequality?
https://math.stackexchange.com/questions/1089191/how-to-prove-cauchy-schwarz-integral-inequality
WEBJan 3, 2015 · The Cauchy-Schwarz integral inequality is as follows: (∫b a f(t) g(t) dt)2 ≤∫b a (f(t))2dt∫b a (g(t))2dt ( ∫ a b f ( t) g ( t) d t) 2 ≤ ∫ a b ( f ( t)) 2 d t ∫ a b ( g ( t)) 2 d t. How do I prove this using multivariable calculus methods, preferably with double integrals? multivariable-calculus. integral-inequality.

WEBThe Cauchy–Schwarz inequality (also called Cauchy–Bunyakovsky–Schwarz inequality) is an upper bound on the inner product between two vectors in an inner product space in terms of the product of the vector norms. It is considered one of the most important and widely used inequalities in mathematics.

WEBApr 13, 2024 · Schwarz's inequality is sometimes also called the Cauchy-Schwarz inequality (Gradshteyn and Ryzhik 2000, p. 1099) or Buniakowsky... Let psi_1(x) and psi_2(x) be any two real integrable functions in [a,b], then Schwarz's inequality is given by |<psi_1|psi_2>|^2<=<psi_1|psi_1><psi_2|psi_2>.

WEB3.4 The Cauchy-Schwarz inequality and a new triangle inequality Recall the triangle inequality on R: |x + y|≤|x|+ |y| for all x,y ∈R. How would this generalize to R2? Let’s view points of R2 as vectors: ~x = (x 1,x 2),~y = (y 1,y 2) be vectors in R2. We define their “norms” as k~xk:= q x2 1 + x 2 2, k~yk:= q y2 1 + y 2.

WEBWhen you square a real number, you get something greater than or equal to 0. When you sum them up, you're going to have something greater than or equal to 0. And you take the square root of it, the principal square root, the positive square root, you're going to have something greater than or equal to 0.
