You stupid fuckwit, according to that definition, there is no
tangent line to f(x) = x at (1,1).
Or to any straight line, at any point.
Because the only possible tangent line will not intersect the curve
(which includes a straight line) in "exactly one point."
Conclusion. You need to kill yourself. There is no other way.
Do it out of the sight of others.
