Visual C++ maths

Sorry, there is no differentiation built-in function in the C++ Standard Library.

Here is what is available in Math:
   http://www.cplusplus.com/reference/clibrary/cmath/

You could try one of these libraries.

Hi All,

                      I am using Visual C++ is there any opensource or free library for thus purpose.

Vimal.

I found this one:
   http://sourceforge.net/projects/calculus/

But this one has more recommendations:
   http://sourceforge.net/projects/gattmath/

What is your exact question? Do you want *formal* or *numerical* derivatives?

HI thehagman,
           
                 I am looking for a good library in windows C++ for applying in differentiation based  problems.

I'm farily sure he wants symbolic calculations (based on other questions he's asked).
Vimal, do you need a C++ library or do you just want a calculator?
This one works well

Also, if you want high tech, you could use MATLAB, Maple, or Wolfram Alpha

Wolfram Alpha is basically awesome. It's like Google for math (and more). Go to it
http://www.wolframalpha.com/
 and type something like
differentiate x^2 + 3x
It will give you the answer and you can click 'show steps' to get the details. It also shows the graph. It does integration too.

Hi TommySzalapski,

                 I need C++ library.
