Critically examine the concept of indefinite integrals (antiderivatives), real functions with one variable (definition of antiderivatives, integration techniques), definite integrals of real functions with one variable (understanding, properties, Fundamental Theorem of Calculus, and improper integrals), use of certain integrals of real functions with one variable (parametric equations, polar coordinates, plane area, arc length, volume of rotating objects, volume of objects whose cross-section is known, rotating surface area, and center of mass) through active learning with the question and answer method assisted by presentation media and Maple.
