It’s Friday. The congregation is gathered at Calculus AB. Mr. Kim is preaching about the virtue of integrals The first fundamental theorem of calculus says: Thou shalt obtain the antiderivative F as the integral of f. The second fundamental theorem of calculus says: Thou shalt subtract function f(a) from f(b) to evaluate the integral from a to b. Mr. Kim shares his testimony – how Mathematics transformed his life and saved him from ignorance. Everyone bows their heads in accord, but will they follow the Word and change their ways?
