Let θ (in radians) be an acute angle in a right triangle and letx and y, respectively, be the lengths of the sides adjacent to andopposite θ. Suppose also that x and y vary with time. At a certaininstant x=7 units and is increasing at 4 unit/s, while y=2 and isdecreasing at 12 units/s. How fast is θ changing at thatinstant?
