Question: Consider the matrix representations for two-dimensional rotations of vectors by angles (alpha) and (beta), denoted by (R_{alpha}) and (R_{beta}), respectively. a. Find (R_{alpha}^{-1}) and (R_{alpha}^{T}).
Consider the matrix representations for two-dimensional rotations of vectors by angles \(\alpha\) and \(\beta\), denoted by \(R_{\alpha}\) and \(R_{\beta}\), respectively.
a. Find \(R_{\alpha}^{-1}\) and \(R_{\alpha}^{T}\). How do they relate?
b. Prove that \(R_{\alpha+\beta}=R_{\alpha} R_{\beta}=R_{\beta} R_{\alpha}\).
