$\int_{1}^{2} x^{-2}dx$
Learn how to solve definite integrals problems step by step online. Integrate the function 1/(x^2) from 1 to 2. Rewrite the exponent using the power rule \frac{a^m}{a^n}=a^{m-n}, where in this case m=0. Apply the power rule for integration, \displaystyle\int x^n dx=\frac{x^{n+1}}{n+1}, where n represents a number or constant function, such as -2. Evaluate the definite integral. Simplifying.
