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
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.
