Hi Mukkul, I have implement the trigonometric terms. only sin and cos. it can add new operator into it easily. this expression d(cos(_x * _x) , _x) will return a functor, at last, the computation is done by std::sin : ) Dongfei.

HI Dongfei,

I am interested in it. But what the plan is exactly ? How you are going to do it for say expressions involving trigonometric terms ? For polynomial expressions things are manageable, how you are going to parse other complex expressions ?

BTW how you are going to take care of algebra at many places ?

With Regards, Reetesh Mukul
