The document describes a program to calculate the area under a curve through numerical integration using rectangular approximations. It gives an example where the function is y=x^2+2x+1 over the domain from 0 to 10, and the user inputs the number of intervals to divide the domain into to compute the approximate area as the sum of the areas of rectangles.

1. - Function: y=x2
- Dividing by 10 interval from 0 to 1
- Result has to be summation of all squares.
•Program for calculating measuration by division. Simple example is below.
On this problem, function is y=x2+2x+1 and domain is from 0 to 10. You must input the number of interval. And print the result.
