# Integration by finding limits?

 P: 290 $$\int_a^b{f(x)}\, \text{d}x = \lim_{n \to \infty}{\sum_{i=1}^n{f(x_i)} \Delta x$$ Is the definition of an definite integral. If she said to find the limit then it seems like she doesn't want you to estimate with a large n value, but to actually find the limit of the sum.
