Just see the effects.
I used an book with a lot of formulas very complicated. But I saw some beautiful graphic functions and I had the idea to create a project with this graphic functions. The book is called "Formulaire et tables" (form and tables). I nikenamed it "le livre de PQR" (The PQR book) because in the thirst page, hese some froms with the letters PQR and with a friend, I nikenamed it like this... If you see thant, Mark, you'll know what I'm talking about...
