Find the Derivative - d/dx 1/(x+1)

Problem

d()/d(x)1/(x+1)

Solution

1. Identify the function as a reciprocal or a power by rewriting the expression using a negative exponent.

1/(x+1)=(x+1)(−1)

2. Apply the power rule and the chain rule, where the derivative of un is n*u(n−1)⋅d(u)/d(x)

d()/d(x)*(x+1)(−1)=−1*(x+1)(−2)⋅d(x+1)/d(x)

3. Differentiate the inner function x+1 with respect to x

d(x+1)/d(x)=1

4. Simplify the expression by multiplying the terms and converting the negative exponent back into a fraction.

−1*(x+1)(−2)⋅1=−1/((x+1)2)

Final Answer

d()/d(x)1/(x+1)=−1/((x+1)2)
