You can see the integral as the limit of a summation as in pic-related. Every rectangle would have height f(x) and width dx, with dx->0. Then, the same principles you can use with summation apply. That is, if you have a sum, such as [math] \sum_{n=-\infty}^{\infty} a_n [/math], but only want the values between a and b, you would do [math] \sum_{n=-\infty}^{b} a_n - \sum_{n=-\infty}^{a} a_n [/math]. You should be able to visualize this.

How do I increase my mathematical visualization ability?

I would like to really visualize problems as I solve them, kinda similar to pic related but in a more complex system.

Is acid the only way?
