Suppose the area of a square is increasing with time.At the time when the side of the square is 4 meters and the change in area is 2 sq meters per min, find the change in the length of the side of the square.

  • calculus -

    a = s^2
    da/dt = 2s ds/dt

    2 = 2(4) ds/dt
    2 = 8 ds/dt
    1/4 = ds/dt
