Mathcad Derivate Wrong Answer

[TW_10163016]

I used the Mathcad to derive equations, but I noticed that the program gives a wrong derivate for the following
d[(x-1)/(4x*(1+x))]/dx, Mathcad gives the answer as [(-x+1)*x'*(x+1)+x(x+1)]/[4x*(x+1)^2], which is wrong. Would you please advise if anything caused such wrong answer?

Thanks!

 Hi,

1. What version of Mathcad are you using?

2. Please upload your worksheet with this example.
