Math ¶

Definition ¶

DEFINITION: (Inverse Matrix)

The inverse matrix $A^{-1}$ of a matrix $A: n \times n$ is defined as a matrix that when multiplied by the square matrix A yields the identity matrix. Note that not always an inverse matrix of a square matrix Q exists.

A^{-1} A \triangleq A^{-1} \triangleq \mathbf{I}

Theorem ¶

THEOREM 1: (Determinant of Orthogonal Matrix)

For any orthogonal matrix^[1] $Q \in \mathbb{R}^{n \times n}$ of n rows and n columns

\det(Q) = 1

Proof

\notag \begin{split} \det (Q Q^T) &= \det(Q) \det(Q^{T}) \\ \det (Q Q^T) &= \det(Q) \det(Q) \\ \det (Q Q^{-1}) &= \det(Q) \det(Q) \\ \det (\mathbf{I}) &= \det(Q)^2 \\ 1 &= \det{Q}^2 \\ \det(Q) &= 1 \end{split}

Solved Exercise ¶

Example: Chain Rule for Derivative Multi-Variate Functions

Let the function f be $f(x, y) = x^2/A^2 + y^2/B^2 - C$ . Find the derivative of f with respect to t. And x and y are functions of t, $x = x(t) = A \cos t$ and $y = y(t) = B \sin t$ .

Solution

\notag \begin{split} \frac{df}{dt} &= \frac{\partial f}{\partial x} \frac{dx}{dt} + \frac{\partial f}{\partial y} \frac{dy}{dt} \\ &= \frac{\partial}{\partial x} (x^2/A^2 + y^2/B^2 - C) \frac{d}{dt} ( A \cos t) \\ & + \frac{\partial}{\partial y} (x^2/A^2 + y^2/B^2 - C) \frac{d}{dt} ( A \sin t) \\ &= (2x/A^2) (-A \sin t) + (2y/B^2) (A \cos t) \\ &= -2x \sin(t) / A + 2y \cos(t) / B \\ &= -2(A \cos(t)) \sin(t) / A + 2(B \sin(t)) \cos(t) / B \\ &= -2 \cos t \sin t + 2 \sin t \cos t \\ &= 0 \end{split}
