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

Problem

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

Solution

1. Apply the sum rule for differentiation, which states that the derivative of a sum is the sum of the derivatives.

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

2. Differentiate the first term using the power rule, where the derivative of x is 1

d(x)/d(x)=1

3. Rewrite the second term using a negative exponent to prepare for the power rule.

1/x=x(−1)

4. Differentiate the second term using the power rule d(xn)/d(x)=n*x(n−1)

d(x(−1))/d(x)=−1*x(−2)

5. Simplify the expression by converting the negative exponent back into a fraction.

−1*x(−2)=−1/(x2)

6. Combine the results from the two terms to find the final derivative.

1+(−1/(x2))=1−1/(x2)

Final Answer

d()/d(x)*(x+1/x)=1−1/(x2)
