If \(T\) is an isomorphism, it is both one to one and onto by definition so \(3.)\) implies both \(1.)\) and \(2.)\). Note the interesting way of defining a linear transformation in the first part of the argument by describing what it does to a basis and then “extending it linearly” to … WebBob Fred. being invertible is basically defined as being onto and one-to-one. theres a difference between this definition and saying that invertibility implies a unique solution to …

WebAn injection, or one-to-one function, is a function for which no two distinct inputs produce the same output. A surjection, or onto function, is a function for which every element in … WebSay you have one matrix that rotates through an angle of π/4 counter-clockwise, then a second one that scales by a factor of 1/2 horizontally, and then a third that rotates back through an angle of π/4 clockwise. The combined effect of all three transformations is to scale by a factor of 1/2 along a line that is inclined at angle of π/4.
