I have the certificate with me at home! My brother, father, and uncles all passed their French BAC exams in Lebanon, while studying under the French Jesuits there.

That's not the correct solution. Cheers Thomas PS: I find it somehow ironic that a CAS is used to solve a system of equations when in fact the exercise is chosen in a manner that this is not needed. Just insert (1, 2) into the definition of f(x) to get a = 2 instantly.

In fact, I wonder if this exercice has been defined in a manner that a student without a brain can still resolve it ;) Edited: 24 July 2013, 10:45 a.m. ▼ Thomas Klemm Senior Member Posts: 735 Threads: 34 Joined: May 2007 07-24-2013, 12:05 PM Do you mean they are easier than the Jewish Problems?

I tried to solve the first ones with the prime and get the instantaneous answers : Problems 4, 5 and 1 : Note that 'solve' also works with inequalities Some interesting problems to try the Geometry Apps but no time for few days ...
