The Fundamental Theorem of Calculus
# Fundamental Theorem of Calculus
# the area under the curve IS the antiderivative at the bounds
# define the "definite integral" (its a tall S)
# talk about what UNITS the integral will have
# task: Compute areas under curves using the FTC
# Just the linearity of definite integrals inherited from antiderivatives
# task: Compute areas BETWEEN curves using the FTC
