Alternatively you could start with x = 1-\frac{4}{t+2} = \frac{t+2-4}{t+2} = \frac{t-2}{t+2}

brah give it a few more weeks :P

You'll eventually get that answer if you use the substitution u = (x-b)

sin^{-1}(\frac{x-b}{a})

I don't think you need to locate the point of inflexion if the question doesn't ask for it. The 2nd derivative is used to determine the nature of the stationary point. (which is probably why the solutions would include that) (if the stat pt is positive in 2nd derivative it's a min pt while a...

The powers of the 4 terms in the first bracket when expanded is x^3 \ \ \ 3x^1 \ \ \ \ 3x^{-1} \ \ \ \ x^{-3} To get the coefficients of x^2 it's (3x^1)({^5}C_1x) + 3x^{-1} ({^5}C_{3}x^3) + x^{-3}( {^5}C_{5}x^5)

If you only plan to do Commerce, then 2U is sufficient :P

Maths would also be very enjoyable if you could do that too :D, you'd also save a lot of time in exams. But yeah then get your tutor the run through the basics in depth (wait is this a private or a class tutor?) before you start tackling the questions, otherwise you would just remember the...

It's an odd function :D well compared to the typical inverse sine function y = sin^{-1}x your graph would be much lower than that in the domain 0 \leq x \leq 1 Once you get that part, use the property that it's an odd function to sketch the left hand side.

Probably because the math problems given are just tedious as mentioned previously, I would get bored as hell if I only got exposed with your MIF questions. Yeah look for past exam papers and harder textbook as enigma mentioned to expand your problem solving skills (if you enjoy that then maths...

To obtain the inverse function, you swap the x and y and then make y the subject. you need to know the log law ln(a)^m = mln(a) so from y = e^x, you swap x and y to get x = e^y , then take the log of both sides to get \\ \\ \\ ln(x) = ln(e)^y = yln(e) = y \ \ \ (ln(e) = y) so idea applies...

I understand that you hate uni. It's much harder than high school and the social life is much harder to handle there since everyone have different times (unless you organise with someone in the same degree before hand to generate the same timetable). However, if you do drop out, what other...

I've been there back in my yr 12 days and let me tell you that I found it pretty lame.

Astro is kinda dodgy I think. Nope I didn't enjoy it, and I despise computing after. Can you elaborate on those subjects?

Hi so I'm a 2nd year student studying adv maths at UNSW. So I'm enrolling for for my 2nd semester and I currently have 2 cores (both maths) and ECON1102 (is this a reasonable course for me as well?). Just wondering what other easy course (relatively) that would be good for my WAM as a...

Best to do that when there are squares involved such as x^2+4x-5 \\ \\ \\ 2cos^2x -2cos x + 1

He wouldn't have learnt that property yet. He would only need equations (1) and (2) that you've mentioned In (1) you find x in terms of a and sub into (2) and solve from there.

This isn't in the 4U syllabus so I didn't learn to rotate around y = x. it depends what integral you'd generate, if you get a much simpler integral from the area of the cross-section, then sure I would go for it.

I added my lab supervisor on fb, and she's pretty cute ;)
