We’ll integrate int 1 / x2 dx by using the power rule.
We will use the power rule to find int 1 / x2 dx.
Explanation:
We have to integrate 1/x2.
We can express 1 / x2 as x−2.
By power rule of integration we know that
∫ an da= an+1 / (n + 1) + C where {n∣n≠−1,n∈R}
So, 1 / x2 dx = −x−1
= −(1 / x) + C
