Contents In this lecture we state and prove the Fundamental Theorem of Calculus. This theorem has that name because it relates derivatives and integrals, the two main branches of calculus. We also discuss some resulting techniques for evaluating definite integrals. Quick Question What is the area under the graph of f(x) = 1/2 + x/2 and above the interval [0,1]? Now let F(x) = x/2 + x2/4; what is F(1) − F(0)?

What is the probability that a random person will score between 1200 and 1250? Find the derivative of a product of a function and an integral. Find the derivative of a product of a function and an integral. Find the integral from 0 to π/4 of tan(x). Use integration by parts to find an expression for the integral from 0 to π/4 of sin(x)5. taking u = (sin(x))4 and dv = sin(x) dx. Find the integral of x2ex.
