The math purist might prefer dF1(T)/dT=X for dF1(T)/dT | T=X. It seems clearer written this way as it shows that you're taking a derivative with respect to a variable, T, then evaluating it at a value, X.

I strongly discourage students from writing things like the above or ∫(F1(x),x,0,x) in which the x has two different meanings. And by "strongly discourage" I mean I take off a token point on a test. :-)
