The Fundamental Theorem of Calculus This One’s a Two-Parter! FTC Part Two First Then FTC Part One
FTC: Part Two…First • If f is continuous on [a, b], and if F is any antiderivative of f on [a, b], then • But we already knew that now didn’t we?!
FTC: Part One • If f is continuous on [a, b], then the function has a derivative at every point x in [a, b], and
FTC: Part One…One More Time • Isn’t ? • And, since F(a) is just a constant w/a derivative of zero, then to take the derivative we just take the derivative of F(x)…which is f(x)!
FTC: Part One…An Example • Find • Find • Find
FTC: Part One…With a Twist…or a Kink! • Apply the second FTC on the integral… • Now take the derivative of (don’t forget the chain rule!)
FTC: Part One…Look at the Kinkage! • So… because of the…CHAIN RULE!!! 2xcos(x2) ZERO!!!
Find Find Find Some More Kinky Problems…
Using Graphs and the FTC • Find h(1).
Using Graphs and the FTC • Is h(0) positive or negative? JYA
Using Graphs and the FTC • Find the value of x for which h(x) is a maximum. Where does f(x) change from positive to negative?
Using Graphs and the FTC This is a graph of f(t) NOT h(x)! • Find the x-values of the inflection points of h(x). Where does the slope of f(x) change?
