Help Request List Standard(s) APC.15​The student will use integration techniques and appropriate integrals to model physical, biological, and economic situations. The emphasis will be on using the integral of a rate of change to give accumulated change or on using the method of setting up an approximating Riemann sum and representing its limit as a definite integral. Specific applications will includea)​ the area of a region;b) ​the volume of a solid with known cross-section;c)​ the average value of a function; andd)​ the distance traveled by a particle along a line.
