hi to all. I would just like to ask if anybody knows a list of difficult mathematical question ? hope you have

Answer 1

Differentiate 1/SqRt (x) using First Principle ONLY. That took 4 math professors/teachers to figure out.

Answer 2

Prove this definite integral identity (Integral is from 0 to 1):
∫[(x^a-1)/ln(x)]dx=ln(a+1)


Yeah, it took me five minutes to differentiate 1/√x using the definition of a derivative . . . I don't think that falls under "difficult." And I think you should talk to someone if it took four teachers to figure it out, that's kinda sad.

Answer 3

Does the equation a to the n plus b to the n equals
c to the n have any whole number answers if n is
greater than 2?

Answer 5

Which topic do you want ?
And forgetful, a/1 != 1
they are not equal

Answer 6

I have one: Please prove that a/1 = 1. Use axioms ONLY...
