Hey Stalkers!


I am Saharsh. A high school science student living in Gandhinagar. My basic interest includes Mathematics, Physics, Chemistry and Computer Science.

These are my academic fields and I am here for helping others over their questions and of course also for seeking some help from my side. If you think I can help you on any issue then please feel free to contact me. I am always right here on stackexchange! :)

You might be forgetting that external users also browse this site and search for the questions. It really doesn't matter how old the question is, people will still find it.

comment Let $f_n(x)=nx(1-x^2)^n$ on $[0,1]$ for $n\ge1$. Find $f(x)= \lim f_n(x)$. Is this a convergence uniform?
Question needs some serious mathjax edit. This is really ambiguous to even edit.

@Integrator It was just to maintain the quality of question. I hope you won't mind that.

revised conversion of $\cos \theta$ = 0.248 without a calculator
changed 1.0471 -> 0.248 (as suggested by the user in the comment); 1.0471 not lie in the range of cos function (and user has just stated this numeral as an example so it's appropriate to change it to some suitable value)

revised Suppose that the area bounded by the curve $y = 3x^2 − 12x + 9$, the x-axis and the lines $x = 1$ and $x = k$ is 16. Find $k$.
mathjax added; changed x=-1 to x=1 (as commented by the asker)

Check the graph. This might help you. desmos.com/calculator/xrghc65aox . Quadratic function is passing through $x$-axis from $x=1$ and $x=3$. You'll have to break the limits accordingly.

comment $\lim_{x \to \infty} x\sin(\frac{1}{x}) = 1$ (epsilon-delta like condition)
Hint: Take another variable $t$ such that $t=\frac{1}{x}$ and change the limit. After that apply the $\sin{x}$ expansion.
