If g = Af, find g for each of these choices of A and f. (a) A=

Question:

If g = Af, find g for each of these choices of A and f.
(a) A= d/dx and f = cos(x2 + 1);
(b) A= 5 and f = sin x;
(c) A = ( )2 and f = sin x;
(d) A = exp. and f = ln x;
(e) A = d2/dx2 and f = ln(3x);
(f) A = d2/dx2 + 3x d/dx and f = 4x3;
(g) A = ∂ / ∂y and f = sin(xy2).
