Really! Let's see if you can pass this short little test. Hell, I
wonder if you can answer any of these questions.

What is this quantity, then?

lim h--> 0 [u(x+h,y) - u(x,y)] / h

Give me one nonzero function that satisfies this differential
equation:

df/dx = f(x)
f(0) = 1

What function is represented by this power series expansion?

1 + x + x^2 / 2 + x^3 / 3! + x^4 / 4! + ....

For alternative credit, explain what a power series expansion is if
you are unable to identify this *simple* function. Hint: It is the
same function as for the previous question.

Evaluate these simple problems:

lim x--> 0 sin(x) / x

int(D(x)dx,x=-\infty...\infty) where D(x) is the Dirac delta function.

int(x^3 dx, x=-1,1)

d/dx * [f(x) / g(x)]

d/dx * [x^n] where n is any number

Giving the answer is unacceptable - you have to prove the answer.

If you can't answer all of these, then why should anyone ever listen
to you?
