Let a and o denote two sides of a triangle and let e denote the included angle. Suppose that a, 6, and e vary with time in such a way tha the area of the triangle remains constant. At a certain instant a = 4cm, b = 8cm, and é =radians, and at that instant both a and . are increasing at a rate of 8cm/s. Estimate the rate at which e is changing at that instant. Round your answer to three decimal places. de rad/s dt
