The Inverse Matrix of a Linear Transformation

Visual Linear Algebra Online, Section 1.9

The inverse of a rotation is another rotation by the same angle, but in the opposite direction.

Inverse functions are a kind of high-technology in mathematics. They can help you solve infinitely many problems at once!

In linear algebra, some linear transformations on finite-dimensional Euclidean space ${\Bbb R}^{n}$ have inverse functions. Those that … Read the rest
