Of course not. School and education is very important for us Germans in contrast to Americans.Don't work for them. Were you sleeping in history class that day? Or did you skip school to hang out with the Deutsche Jugend?
Tell me. What are the solutions of this equation?
d f(x, y)/dx+d f(x, y)/dy =delta(x-a)*delta(x-b)
with delta(x-a) as the deltafunction.
Now you can prove how intelligent Americans are and that is still an easy task.
