    Derivative of sin(x)/(1+x^2) using Chain Rule | Simple Homework Example

    Sorry! I see how that can be confusing. It's \ \displaystyle f(x)=\sin\left(\frac{x}{1+x^2}\right) I am working on trying to put in equations correctly

    Derivative of sin(x)/(1+x^2) using Chain Rule | Simple Homework Example

    Homework Statement Use chain rule to find the derivative of f(x)= sin(x)/(1+x^2) Homework Equations Chain Rule (f(g(x)))'*g'(x) The Attempt at a Solution y'(x)= cos (x)/(1+x^2)* (1-x^2)/((1+x^2)^2) I just want to make sure I am doing it correctly and this would be acceptable as a final answer.
