for the following curves: ey = x, sin (y) = x, cos(y) = x. dy Determine dxA boat sails directly toward a 150-meter tall skyscraper that stands on the edge of a harbor. Let :1: be the horizontal distance between the base of the building and the boat. The angle 6, measured in degrees, is the angle of elevation from the boat to the top of the building. (a) Sketch picture of this situation (b) If the angle of elevation is 45, how far from the building is the boat
