How do you use the trapezoidal rule with n=2 to approximate the area between the curve #y=x^2# from 1 to 5?
34 square units
The problem is perhaps to find the area between the given curve and the x axis, from x=1 to x=5, with two intervals.
With n=2, the two intervals would be from x=1 to x=3 and from x=3 to 5. The two trapezoids so formed would have a width of two units.
Sum of the area of two trapezoids would be
= [1+9+9+25]= 34 square units.
