1 Definite Integrals 5.6 “u” substitution

2 The First Fundamental Theorem of Calculus
To understand this, lets do a problem in 2 steps: Find F(x): Find F’(x)

3 The First Fundamental Theorem of Calculus
If f is continuous on [a,b] then is differentiable on every point in [a,b] and

4 Rules

5 Examples – Find dF/dx

6 u substitution We’ve talked about this a little; as you substitute “u” in, the limits of integration will change. Lets look at a few examples to see how these work:

7 Examples

8 Do you have to do this? No, you don’t. It just sometimes makes some very unwieldy problems look nicer and simplify quicker.
