x + x + x + .... +x (added 'x' times) = x²
Differentiating both sides with respect to x, we get:
1 + 1 + 1 + 1 + .... + 1 ('x' times) = 2x
(Since the derivative of x² with respect to 'x' is 2x).
So we now have:
x = 2x
Cancelling 'x' from both sides, we have:
1 = 2
Now the very obvious question follows:
Where is the flaw ?
