L34 - 6 Net Change Theorem The integral of a rate of change of a function is the net change of the function on the interval [a,b]: ▯ b ▯ F (x)dx = a ex. If the volume of water in a lake is increasing at the ▯ rate V (t), then ▯ t 2 ▯ V (t)dt = t1 gives dn ex. If a population is growing at a rate of dt ,en ▯ 2 dn dt = t1 dt gives
