Let 0 (in radians) be an acute angle in a right triangle and let z and y respectively, be the lengths of the sides adjacent to and opposite 0. Suppose also that z and y vary with time. At a certain instant z =7 units and is increasing at 4 unit/s, while y = 4 and is decreasing at units/s. How fast is 0 changing at that instant? Answer:
