Question: (a) Express dw/dt as a function of t, both by using the Chain Rule and by expressing w in terms of t and differentiating directly

(a) Express dw/dt as a function of t, both by using the Chain Rule and by expressing w in terms of t and differentiating directly with respect to t. Then 


(b) Evaluate dw/dt at the given value of t.W = x + y, x = cost + sin t, y

W = x + y, x = cost + sin t, y = cos t - sin t; t = 0
