Why does definite integral have the operation subtraction? Does the definite integral always have to involve finding the area and if not, why?
For examplef' or f prime = [f(b) - f(a)] ÷ (b - a) = The integral from a to b and f'(x)dx or f prime dx Divided by (b - a)No area is being found. I hope there are better examples. I'm sorry
