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! :)

comment Unique intersection of $b^x$ and $\log_b(x)$
@SimonS user had specified that the point $b>1$ and there is exactly one point of intersection. Thus for $b>1$ there is only and only one value where there is one point of interesection.

comment Probability of a point lying in a space
@Eupraxis1981 Yes. "The points have integral co-ordinate". And please don't consider any relativity errors.

comment Calculate $\sin{55}-\sin{19}+\sin{53}-\sin{17}$ without calculator
Thank you. This was the identity which I was missing. Silly me.

@Jihad Yes. It's in degrees.

@Integrator All right. Thanks!

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?
Please add mathjax for clarification. Refer this page for edit: meta.math.stackexchange.com/questions/5020

@Integrator You are just seeing. Realizing is more important. This was my favorited question, hence I rectified it. And other way moderator himself had approved this edit. He would have judged whether it's correct or not. And by the way does it harm anyone if the question appears on the main page (any kind of server fault or other inconvenience), definitely not. This was a reasonable edit.

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.

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.

comment 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 $k$.
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.

Sorry to not to inform earlier. I had made an edit. I am completely unfamiliar with the modular arithmetic.

comment How to evaluate $(0.9)^4$ without calculator
Of course there is no single way to solve the problem and that's the beauty of mathematics but do you think this answer have been a useful submission to the asker. Please don't consider me a revolutionist, it's just a comment after all.

comment How to evaluate $(0.9)^4$ without calculator
Where is the binomial method? I think you missed that while reading the question (if you 'actually' read it).

@HansLundmark This was what I was seeking for. Thanks.

I of course know what's the difference. Imaginary is the subset of complex and it's not my doubt either. Please read the complete question with patience.

@Alan can you explain some examples in a bit detail. Your efforts will be appreciated. Thanks :)

@JBKing Origin of Quaternion is something similar to square root of negative. Isn't it? Keep that function aside right now. I want to know it with some other functions.

comment How to solve system of Differential Equations with 1 independent and 3 dependent variables
I don't know whether it'll help or not but terms can be simplified to $$\frac{B''(t)}{B(t)}+\frac{F''(t)}{F(t)}+\frac{B'(t)F'(t)}{B(t)F(t)}=0 ------- (1)$$ $$\frac{A''(t)}{A(t)}+\frac{F''(t)}{F(t)}+\frac{A'(t)F'(t)}{A(t)F(t)}=0 ------ (2)$$ From (1), (2) and your third equation, $$2\frac{F''(t)}{F(t)}+\frac{B'(t)F'(t)+A'(t)F'(t)}{A(t)F(t)}=0$$
