 Dec7 comment How to become proficient in Calculus? ocw.mit.edu/ans7870/resources/Strang/Edited/Calculus/… should be the correct link Dec7 comment How to find a general sum formula for the series: 5+55+555+5555+…? @Winther Thanks. I never thought I would learn about a word on math.stackexchange. Everyday is a new day of learning :) Nov18 comment How to find a general sum formula for the series: 5+55+555+5555+…? @Winther is increasibly a new word? Nov11 comment If $ax + by ≤ bx + cy ≤ cx + ay$ then $b ≤ c$ USAMTS is a competition and the user calcstar is violating the rules of competition. The moderators on Stackexchange have to disable these activities in future. Dec24 comment How can one prove that $e<\pi$? Very creative and interesting way to look at the problem. Dec24 comment Find all solutions of $1/x+1/y+1/z=1$, where $x$, $y$ and $z$ are positive integers Thanks @user44197. I got 10 possible values for which k is integer actually by your approach. $(x_0,y_0,\mu)$ as ${(1,1,1),(1,2,1),(2,1,1),(2,3,1),(3,2,1),(1,1,2),(1,3,2),(3,1,2),(1,2,3),(2,1,3‌​)}$ Dec23 comment Find all solutions of $1/x+1/y+1/z=1$, where $x$, $y$ and $z$ are positive integers If you edit your answer, make a comment in this chain of question for some users who might look at this later Dec23 comment Find all solutions of $1/x+1/y+1/z=1$, where $x$, $y$ and $z$ are positive integers So basically you are same thing as @mathlove Dec23 comment Find all solutions of $1/x+1/y+1/z=1$, where $x$, $y$ and $z$ are positive integers You probably mean cannot exceed 6 Dec23 comment Find all solutions of $1/x+1/y+1/z=1$, where $x$, $y$ and $z$ are positive integers But some solutions like (2,3,6) (3,2,6) does not say none should exceed 5 Dec23 comment Find all solutions of $1/x+1/y+1/z=1$, where $x$, $y$ and $z$ are positive integers Yes that was a mistake (I can't believe I said that - looks so stupid of me) Dec23 comment Find all solutions of $1/x+1/y+1/z=1$, where $x$, $y$ and $z$ are positive integers they have to be less than 1 isn't it? How can x,y,z be greater than 1? May28 comment Teenager solves Newton dynamics problem - where is the paper? Wiki says that his dad taught him Calculus at the age of 6 (Really??) - That probably beats all the records. May23 comment How to find values of constants in the definition of a function given that function's stationary points? Are you sure those stationary points are correct? May23 comment Summation of Infinite Series $\sum_{n=1}^{\infty} \frac{1}{n 2^{2n+1}}$ Did you try $\sum_{n=1}^{\infty} \frac{y^n}{n} = -\ln \left(1-y\right)$ May19 comment Help Understanding Solution? (Putnam and Beyond) Doesn't this book also provide solutions. (Solution to your question on page 367) May19 comment Mid-step in solving a pde @morphism it was a silly error, I corrected it. May18 comment Approximation for $\pi$ What are you expecting, validation of this approximation and some sort of variation of this approximation? May18 comment Approximation for $\pi$ Another interesting discussion (related) here math.stackexchange.com/questions/108510/… May18 comment Generalizing an approach to proving AMGM Instead of going so far (generalizing), why don't you try for $n=4$ and share your answer
