Re: HSC 2016 3U Marathon Hint: \tan^2{x} +1 = sec^2{x} $ May be needed. $

I think it may be a more reasonable answer to say that since the circle experiences friction it has done work as friction is a non-conservative force. EDIT: NVM didn't read your last line :P...

$ What I would do (which is probably wrong) : $ $ Consider cases if $ f(x) \rightarrow 0 $ as $ x \rightarrow a $ and $ f(x) \rightarrow \infty $ as $ x \rightarrow b $ Then there is a minimum value between $ (0,\infty ) $ since $ f(x) >0 $ there is such a y value $ c $ which $ f(x) \geq c...

Re: HSC 2016 2U Marathon Cases is the way to go.

Since LHS in the expression is >1 subtracting by one reduces the value of the expression. LOL jks we dont know this.

\text{You have} |f(x)-L|=\frac{1}{2}| \frac{2\sin^2{\frac{x}{2}}}{x^2}-1 | $ Upon the omission of the $ -1 $ we introduce an inequality $ |f(x)-L| < |\frac{sin^2{\frac{x}{2}}}{x^2}| $ Eliminate the sin $ \ |f(x)-L| < \frac{1}{x^2} |f(x)-L| < \frac{1}{M^2}= \epsilon $ For some $ x>M...

Slight correction, at C that's where the inequality is introduced.

Why you cut?

Re: HSC 2016 2U Marathon My bad :P You would just draw the 2 graphs and add their ordinates separately.

How do you find the shortest distance in vectors. 1. How to derive it for a point to a line(in Cartesian form vs parametric form) 2. From line to line (Cartesian vs parametric)

Re: HSC 2016 2U Marathon Auxiliary form.

"Believers cannot serve their cause through politics in such stormy circumstances. Whatever service is rendered for Islam through politics eventually benefits the dominant anti-Islamic system, because foreign powers control the reins of political life. Engaging in politics also divides Muslims...

A wise man once said, "Writing notes for maths is like wearing a raincoat in a shower."

I end this roast with a final quote I made that you should memorise and recite every day before you go to sleep. It may take a whole life time to establish a good reputation; but as you have seen Leehuan it takes 1 night to ruin one.

Oh god ahaha fake account or the real leehuan ?:o Sorry Lee, I usually dont roast people but you've been speaking as if you're the smartest person in the world... Just remember just this year there were more than 1000 people who beat your atar and they're only in NSW... Compare yourself with...

I have a poster of him in my room he signed "your atars not good enought for me"
