1 Your graphing calculator can be used to evaluate definite integrals:
=fnInt(f (x),x,a,b) Math 9

2 Example: MATH (9:) fnInt( MATH

3 Numerical Integration
MATH (9:) fnInt( fnInt(f (x), x, a, b) gives Try , compare to the computation using the Fundamental Theorem MATH

4 Numerical Integration

5 Numerical Integration
You can also estimate the value of the definite integral while looking at a graph. First graph

6 Numerical Integration
CALC (2nd TRACE) #7 This is the definite integral even though the notation is wrong.

7 Numerical Integration
Enter the Lower Limit Press 1 then ENTER

8 Numerical Integration

9 Numerical Integration
Then the Upper Limit Press 3 then ENTER

10 Numerical Integration
Then the Upper Limit Press 3 then ENTER There’s your answer!
