We need to find the derivative of 1/x2
We know that 1/x2 can be written as x-2
To solve the above differential we will use the power rule.
This is one of the most common rules of derivatives. If x is a variable and is raised to a power n, then the derivative of x raised to the power is represented by:
d/dx(xn) = nxn-1
So let us consider y = x-2
By sing power rule we get
Derivative of 1/x2= -2/x3
