Prove the schwarz inequality

Webb5 sep. 2024 · Before making a metric space, let us prove an important inequality, the so-called Cauchy-Schwarz inequality. Take and . Then Any square of a real number is nonnegative. Hence any sum of squares is nonnegative: We relabel and divide by 2 to obtain which is precisely what we wanted. Let us construct standard metric for . WebbWell, this would be fine, but the thing is that we usually define the the angle between two nonzero vectors a and b in n-space to be the number x for which cos x = a · b / ( a b ), …

WebbSo the triangle inequality states that the length of the third side is less than the sum of the lengths of the other two sides. This is a classical theorem of Euclidean Geometry, written in terms of vectors. Part (b): Use the Cauchy{Schwarz inequality j~a~bj j~ajj~bjto prove the Triangle inequality.
