3 Preview The problems from this section are at most at pre-cal level. It was moved, in the 6 th edition, from section 9 to section 7. We will look at how to find the formula in additional to verifying the formula.

4 Two Common Ways… 2 ways to introduce a mathematical fact… 1. Verification 2. Show (Prove)

5 Two Common Ways… 2 ways to introduce a mathematical fact… 1. Verification 2. Show (Prove)

6 Two Common Ways… 2 ways to introduce a mathematical fact… 1. Verification 2. Show (Prove)

7 Two Common Ways… 2 ways to introduce a mathematical fact… 1. Verification 2. Show (Prove)

8 Definitions Differential Equation (D.E.): An equation involves derivatives Initial Value Problem (IVP): A D.E. with an initial condition Section 9

9 Example 1 D.E. IVP

10 Theorem The solution of is where c is some constant.

11 Solutions In addition to verification as done in the book, we are going to look at how to actually show that there are no more solutions.
