Question 3. An n×nmatrix is called orthogonal if it is invertible and its transpose is its inverse. That is, Qis an orthgonal matrix, if QT = Q−1. Show that the matrix Q= cosθ −sinθ sinθ cosθ is orthogonal for any number θ. (Don’t fixθ, just let it be θ.)

Inverse means to undo or do the opposite of what has been proposed. In math we have learned that this is the concept of forming a reciprocal where the numerator and denominator switch positions. When we apply this concept to matrices, the inverse of a matrix is the matrix when multiplied by itself, results in the identity.
Note: Not every square matrix will have an inverse. If a square matrix does not have an inverse, then it is said to be singular. How to Find the Inverse of a Square Matrix 1. Adjoin the square matrix A with the identity matrix of the same size, [A I|]. 2. Use the Gauss-Jordan elimination method to reduce [A I|]to the form [I B|], if possible ...

Relevance to Matrix Equations: The inverse of a matrix allows you to “reverse engineer” a matrix equation, in the sense that if Ax~=~band Ais invertible, then x~= A 1~bis a solution to the original equation. In fact, it is the unique solution to the equation! 2 Use the inverses computed previously to solve these matrix equations: (a) " 0 1 ...
