Feb 27	comment	Find the length of the curve: $y=\frac{x^{5}}{6}+\frac{1}{10x^{3}}\qquad 1\leq x\leq 2$ @Tavares, yes it is
Feb 27	comment	Find the length of the curve: $y=\frac{x^{5}}{6}+\frac{1}{10x^{3}}\qquad 1\leq x\leq 2$ ok now i see. so then the integral would be sqr[(25x^8)/36 + 1/2 + 9/(100x^8)]
Feb 27	comment	Find the length of the curve: $y=\frac{x^{5}}{6}+\frac{1}{10x^{3}}\qquad 1\leq x\leq 2$ @Tavares where does the 1/2 come from?
Feb 27	comment	Find the length of the curve: $y=\frac{x^{5}}{6}+\frac{1}{10x^{3}}\qquad 1\leq x\leq 2$ It is 1/(10x^3)

Feb 25	comment	Number Theory - Proof of divisibility by $3$ ahh i see now. makes perfect sense. thanks
Feb 25	comment	Number Theory - Proof of divisibility by $3$ @yunone, how could you prove that 3\|x by using x=y(mod 3) if 3\|(x-y) only

Feb 25	comment	Number Theory - Proof of divisibility by $3$ Yes i do that if x = y(mod3) then x and y divide 3?

Feb 18	accepted	Injective and Surjective Functions
Feb 18	comment	Injective and Surjective Functions thanks. it makes sense to create a proof that includes all possible cases.
Feb 17	comment	Injective and Surjective Functions I edited my proof for a. Please confirm that this is valid.
