 Oct 20 comment What is the use of Calculus? I don't think this really counts as a real-world application of calculus. Oct 6 awarded Civic Duty Oct 6 comment Find the real and imaginary parts of $z^{22}=\sqrt{3} - i$ No, not multiplying by 1/22. 22nd root: $$\sqrt[22]{z^{22}}=\sqrt[22]{2e^{-\frac\pi 6 i}}$$ Oct 5 comment Find the real and imaginary parts of $z^{22}=\sqrt{3} - i$ @bah Have you tried taking the 22nd root? Oct 5 answered Find the real and imaginary parts of $z^{22}=\sqrt{3} - i$ Aug 2 comment What is the actual geometric meaning of trigonometric operations such as adding cos,sine,tan @oemb I'm not sure I understand, but if I do, then yeah, since $r=1$, they are just the $x$ and $y$ lengths. Jun 16 comment Ideal amount of piles to sort a stack of 250 cards (magic the gathering) Is the machine controlled by electronics? Because if so, you only need two piles to do a sort in-place in the stack. Jun 2 comment Show that the question “Is there life beyond earth?” is decidable Could you please include a proof that the set of all possible universes is countable? Apr 9 awarded Organizer Apr 9 revised Is $\exp(x)$ the same as $e^x$? The question doesn't have much to do with calculus or derivatives - just notation Apr 9 suggested approved edit on Is $\exp(x)$ the same as $e^x$? Mar 27 suggested rejected edit on How is Euler fluids equation considered unsolved? Mar 17 comment Probability of another 3 integers with same sum and product as the first 3 integers @Henry The title says "same sum and product", which is why I concluded that, though I agree it is mildly unclear. Mar 17 comment Probability of another 3 integers with same sum and product as the first 3 integers @Henry Unfortunately not quite what the question is asking. It's asking for $xyz=x+y+z$. Mar 14 awarded Yearling Mar 4 comment How to tell where parentheses go in functional notation? @WChargin Physics has slightly different conventions than math for this. Usually, if parentheses are omitted in physics, you parenthesize all terms up until the $t$ term. Jan 24 awarded Nice Answer Dec 25 comment Easy example why complex numbers are cool I seem to recall a use of complex numbers in the book "One, Two, Three, Infinity" which fascinated me, but I don't quite recall it. It concerned a treasure map referencing a guillotine that had disintegrated, but using complex numbers worked regardless... Dec 21 comment What are some mathematically productive ways to waste time? Can we please try to give more than one-line answers to this question? Dec 19 awarded Constituent
