comment conversion of $\cos \theta$ = 0.248 without a calculator
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.
