The table on the board shows the rate of lemonade consumption in gal/hour from a summer spree. The function for the rate of lemonade consumption is given by R(t) and is a twice differentiable and strictly increasing function. From the table on the board approximate how many gallons of lemonade were used from time 1 to 13 using a left endpoint reimann sum. Be sure to answer in the correct units. Is your approximation an under approximation an over approximation? Write an equation for the exact amount of lemonade consumed from hour 3 to hour 8 given R(t).
-402gal. -This is an under approximation because the function is strictly increasing and we used a left end point approximation. -The integral from 3 to 8 of R(t)dt

Explain clearly how the fundamental theorem of calculus helps to evaluate integrals and leads to the second fundamental theorem of calculus.
The first fundamental theorem of calculus says that the derivative of an integral function is the integrand function. Thus, the integral function itself is equivalent to any antiderivative of the integrand function. This leads us to the second fundamental theorem of calculus which explains how to evaluate definite integrals by finding the antiderivative, and subtracting the antiderivative evaluated from a to b - (in subtraction the constant is cancelled out.)
