In the previous post we have shown an F# program that calculates derivatives. It has a room for improvement in its presentation part: resulting expressions often can be rewritten in a simpler form, and F# suits very well to solve such task. We will be...
I am learning F#, and one of the best areas to use a functional language is to apply it to symbolic calculations. Like evaluating function derivatives. I remember how I was impressed many years ago when I looked at a program in Prolog that occupied not...
