Trapezium Rule

Question 1

Intergrate curve y (in term of x) with limit 0 and 3 for 3 intervals.

Answer 1

Use formula 1/2 h { (y1+yn) + 2(y2+y3+y4+…) }

h (height of each small trapezium) = 3-0 / 3 = 1.

Cut big trapezium to 3 small trapezium, find x for each parallel line by add 1 to the previse x value.

Sub x to find y.
y is the length of each parallel line of all small trapezium.
