How to use Math.Exp(x)?

[damkiidmki]

How to use correctly Math.Exp(x), example:

Expression<Func<double, double>> f = x => Math.Exp(Math.Pow(x,2))+1/x; Console.WriteLine(f.Simplify()); Console.WriteLine(f.Differentiate());

I have (System.Exception: "Failed to convert to expression: (x*%e^x^2+1)/x")
