We (Natalia, Johanna, Julia and Sandra) 4 girls from Munich, Germany, want to present an useful maths topic. The 4 of us finished the 11th grade at secondary school. Today we are at school in the room where a lot of computers are and we are creating a page with an useful maths topic. The "Ableitungsregel" or " Kettenregel" in german is also very important for our school exam, which is in two years. You can see one exercise, which we had created ourselves, about the "Kettenregel". We would be very pleasured if you give us an feedback about our exercise...
Nice greetings from the very hot munich
Johanna, Julia, Natalia and Sandra
