In this activity, students explore the connection between an accumulation function, one defined by a definite integral, and the integrand. They also discover that the derivative of the accumulator is the integrand.
Students will evaluate an accumulation function using list variables in the graphing handheld.
Students will see that a minimum on the accumulator occurs where the integrand changes sign from negative to positive.
