Looking at a question which is currently on front page, maybe my suggestion here was not entirely out of place: Would disallowing displayed equations (“double dollars”) in titles be useful?

Q: $$\frac{\mathrm d}{\mathrm d X}[\mbox{tr}(-(CX(X^TCX)^{-1})(A+A^T)(X^TCX)^{-1})]= \,\, ?$$

mohammad saeediI want to obtain the derivative of the trace of the following statement with respect to matrix $X$ $$\frac{\mathrm d}{\mathrm d X}[\mbox{tr}(-(CX(X^TCX)^{-1})(A+A^T)(X^TCX)^{-1})]= \,\, ?$$ where $C$ is a symmetric matrix. I doubt that my calculation is correct, so I'm grateful for your help. ...

It's huge. (As Bernie Sanders would say.)
