Final Answer
The integral diverges.
Step-by-step Solution
Problem to solve:
$\int_{-2}^{1}\frac{1}{x^2}dx$
Specify the solving method
1
Since the integral $\int_{-2}^{1}\frac{1}{x^2}dx$ has a discontinuity inside the interval, we have to split it in two integrals
$\int_{-2}^{0}\frac{1}{x^2}dx+\int_{0}^{1}\frac{1}{x^2}dx$

$\int_{-2}^{0}\frac{1}{x^2}dx+\int_{0}^{1}\frac{1}{x^2}dx$
Learn how to solve problems step by step online. Integrate the function 1/(x^2) from -2 to 1. Since the integral \int_{-2}^{1}\frac{1}{x^2}dx has a discontinuity inside the interval, we have to split it in two integrals. The integral \int_{-2}^{0}\frac{1}{x^2}dx results in: \lim_{c\to0}\left(\frac{1}{-c}-\frac{1}{2}\right). The integral \int_{0}^{1}\frac{1}{x^2}dx results in: \lim_{c\to0}\left(-1+\frac{1}{c}\right). Gather the results of all integrals.
Final Answer
The integral diverges.
