help with array

Question

You will write a program that evaluates the integral of sin(x) using the left-hand rectangle rule with 2000 subintervals, over 10 intervals. The intervals to test are [0, 1), [1, 2), …, [8, 9), [9, 10). You will declare an array of type double that can hold 10 elements, and you will use this array to hold all 10 results you get from evaluating each interval.

I am in testing my code, what should be the output? For example, [0, 1)? Any idea?

Thanks.

Answer 1

In case of a sin function you should be able to figure it out. For more complicated cases use this tool:
