Suppose a lightbulb is slowly dimming, and the intensity of its light is decreasing according to dl/dt = 0.5t - 3 candela per second. Determine the exact net change in the light's intensity during the first minute.
This question will use definite integration. We know the rate of change of intensity, and we want to know the net change in intensity. We should integrate dl/dt from t=0 to t=60 seconds
