Each problem set was lovingly crafted, and each problem helped me understand the material (there weren't any "filler"; problems or long derivations where I learned nothing). Solution: (a) \[\nabla f(x) = Ax + b\] The calculation involved is by default using denominator layout. Remember, you should address why your explanation. For an eigenvalue $\lambda_i$ of $A$ and its corresponding eigenvector $v_i$, we have $v_i^TAv_i=\lambda_i v_i^Tv_i\geq 0$ since $A$ is PSD and $Av_i=\lambda_iv_i$.
