6-3 Definite integrals & antiderivatives
Rules for Definite Integrals Order Zero Constant Multiple Sum & Difference
Rules for Definite Integrals Additivity (transitive-ish) Max-Min Inequality Domination Use 1 – 5 the most
Ex 1) Suppose Find each of the following integrals, if possible. a) b) c) d) Not enough info
Ex 2) (Min-Max Inequality) Show that the value of Max value of 1
Def: Average / Mean Value The average / mean value of f (x) on [a, b] is Ex 3) Find the average value of f (x) = 4 – x2 on [0, 3]. Does f actually take on this value at some point in the given interval? Not a coincidence! Check out next Thm! fnInt Is f (x) = 1 anywhere in [0, 3]? 4 – x2 = 1 3 = x2 Yes! f (x) = 1 when
Thm: Mean Value Theorem At some point c on [a, b], *Let’s make some connections with what we’ve learned so far… (Note: F stands for any antiderivative) *deriv & integral are opposites * F is the antiderivative of f To find C, let x = a 0 = F(a) + C –F(a) = C So…
Ex 4) Find using the formula
