Ahiker is hiking in a valley. the height of the valley is h(x, y)=4x2+y2 where x and y are the east-west and north-south distances from the valley floor respectively. the hiker follows an elliptical path x(t)=2 cos(t), y(t)=4 sin(t) around the valley. compute the time derivative of the height in two ways. first expand the composite function h(x(t),y(t)) explicitly in terms of t. second use the chain rule.
