For the following functions f: R^3 rightarrow R and g: R rightarrow R^3, find nabla f and g' and evaluate (f compositefunction g)' (1). f(x, y, z) = xz + yz + xy, g(t) = (e^t, cos(t), sin(t)) nabla f = g' = (f compositefunction g)'(1) = f(x, y, z) = e^xyz, g(t) = (9t, 5t^2, t^3) nabla f = g' = (f compositefunction g)'(1) = f(x, y, z) = (x^2 + y^2 + z^2)log(Squareroot x^2 + y^2 + z^2), g(t) = (e^t, e^-t, t) nabla f = g' = (f compositefunction g)'(1) =
