Trapezium rule

Question 1

If there are 5 ordinates, how many strips are there?

Answer 1

4

Question 2

How do you find h (height) ?

Answer 2

h = (b - a) / n

Question 3

What are the steps for using the trapezium rule?

Answer 3

Menu on calc and click table
type eqn in q into f(x)
leave g(x) blank
Ordinates will give you start and end value
value of h gives you val for step
put results into table, first and last in ends column, other values in middles
add the ends together
add the middles together
total area = 1/2h (ends + 2(middles))

Question 4

How do you work out the total area?

Answer 4

1/2 (h) (end + 2(middle))
