 Oct16 suggested approved edit on $\mathbb Z^n$ as a proper quotient of $\mathbb Z^m$ Oct7 awarded Good Question Sep23 comment Not understanding how to factor a polynomial completely @Cherry_Developer No it should be: $P(x)=(2x-3)(2x+3)(4x^2+9)$ Sep18 comment Probability of 7 Card Hand with All Different Ranks? The first card is from 52, then subtract 4 each time? Just a thought but i think it would be: (52*48*44*40*36*32*28) should might be the top? The first card should still be included in the multiplication? Not that sure, but maybe this helped? Sep15 awarded Benefactor Sep15 accepted Intuitively, how do you explain the concept of Flux? Sep15 comment Intuitively, how do you explain the concept of Flux? Could you possibly expand a bit more on this? I'm having a bit of trouble visualizing how it would work or a simple example of numbers or such? Sep14 awarded Promoter Sep13 revised Intuitively, how do you explain the concept of Flux? corrected spelling Sep12 asked Intuitively, how do you explain the concept of Flux?

Jul18 suggested approved edit on How to solve a system of three nonlinear equation in a simple way Jul14 comment Using the Chain Rule to prove trig derivatives @YvesDaoust I see, that makes sense. Jul14 comment Using the Chain Rule to prove trig derivatives @YvesDaoust Really? Why? I've never seen the $\circ$ for my derivatives when doing them in class/examples.
