Problem 4: Variations: optimal Kalman gain and error covariance [3 pts] From Lecture 08, we learned there are two expressions of $K_k$ and three expressions of $P_k$, and we have derived one of each in Lecture 07 as follows: $K_k = P_{k-1}H_k^T(R_k + H_kP_{k-1}H_k^T)^{-1}$ $P_k = (I - K_kH_k)P_{k-1}(I - K_kH_k)^T + K_kR_kK_k^T$. Please derive the rest. $K_k = P_kH_k^TR_k^{-1}$ $P_k = (P_{k-1}^{-1} + H_k^TR_k^{-1}H_k)^{-1}$ $P_k = (I - K_kH_k)P_{k-1}$
