6-4 Day 1 Fundamental Theorem of Calculus
The Fundamental Theorem of Calculus has 2 parts *The Fundamental Theorem of Calculus has 2 parts. One part relates derivatives and integrals and the other establishes how we evaluate integrals by hand. Fundamental Theorem of Calculus: Part 1 Every continuous function f is deriv of some other function Every continuous function has an antiderivative Integration & differentiation are inverses of each other
Ex 1) Using the Fundamental Theorem of Calculus, find: a) b) Ex 2) Find (Use chain rule!)
Ex 3) Find a) b) (variable lower limits)
Ex 4) Find a function y = f (x) with derivative that satisfies the condition f (3) = 5. Since y (3) = 0 We need to add 5 *Note: We can graph the integral of a function by using fnInt. Just put x as the upper limit.
Fundamental Theorem of Calculus: Part 2 (Integral Evaluation Theorem) *says any definite integral of any continuous function can be calculated without taking limits or Riemann sums – so long as antiderivative can be found Ex 5) Evaluate (can check with fnInt)
Ex 6) Find the area of the region between the curve y = 4 – x2 , 0 x 3, and the x-axis.
To find Total Area Analytically Partition using zeros Integrate each subinterval Add up absolute values To Find Total Area Numerically Use fnInt with absolute value Ex 7) Find the area of the region between the curve y = x cos 2x and the x-axis over the interval –3 x 3 Use Math 9: fnInt (abs (x cos 2x), x, –3, 3) abs value Math Num 1
