Can you please help me with detailed solution to this problem?

5.8 Compute the derivatives df/da of the following functions. Describe your steps in detail. a. Use the chain rule. Provide the dimensions of every single partial deriva- tive. f(z) = exp( -= =) z=g(y) =y s ly y = h(@) = =-/ where a, HER", SE RDXD. b. f(x) = tr(xx to'[), DE RD Here tr( A) is the trace of A, i.e., the sum of the diagonal elements Aji. Hint: Explicitly write out the outer product. c. Use the chain rule. Provide the dimensions of every single partial deriva- tive. You do not need to compute the product of the partial derivatives explicitly. f = tanh(z) E RM z = Ar+b, GER, ACRMXN, bERY. Here, tanh is applied to every component of z
