WDHMBT????

If you ironically think Real Analysis is indistinct from the trash engineer tier burgercourse I recommend suicide to save yourself from massive embarrassment.

>>he's proud of taking a formula monkey course and then waiting four fucking semesters before doing actual math with real numbers
I'm not a "he".

I know you're an "it," you filthy subhuman.

holy shit that's uncanny

But user,

For n!, the limit as n approaches -1 from the right is infinity. From the left, it is -infinity.

e^-1 ≈ 0.36787944117

0.36787944117 is not even close to ∞ or -∞

I don't know where OP got this retarded approximation either.

I think physicists usually write [math] \sin^{-1}\,(x)=\arcsin\,(x) [/math]
