Hi, I am not really a per— oh wait. I am this 13 year old guy who relaxes all the time — not sure if has a real purpose in life.
I like to study mathematics and physics and will do some work on these interesting fields in the future. Currently targeting physics.

Algebra Equation with equals on left hand side @amWhy Just saying, but some people who have started with algebra-precalculus may not understand what a relation is, let alone a symmetric relation. I think you should include a link which explains equivalence in classical logic as well as relations. Thanks :-) |

How do you define definition symbol :=? := := :=, if you know what I mean. ;-) |

What is $-i$ exactly? @AdrianPetrescu but 1 does have a sign, which is +, so we can use - to negate it. Here, I first focus on how -i cannot exist and then I say that even if it does, what differences are there between the two? |

How to show $x^4 - 1296 = (x^3-6x^2+36x-216)(x+6)$ Uh, actually I am saying that you wrote $a^4 - b^4 = a^3 + a^2 b + ab^2 + b^3$. It should be $a^4 - b^4 = (a - b)(a^3 + a^2 b + ab^2 + b^3)$ |

Choice of numbers in calculating $\lim_{x\rightarrow 0}\frac{e^{2x}-1}{\sin 3x}$ I think what lab said suffices. |
