I wonder how many people understand the Taylor's series beyond the application of the formula?

I'll wait for your explanation.

You can also prove it using the triangle inequality - ala 2000 HSC Q7b

Have you ever met a murderer? If not, do you hate them nevertheless?

You are an idiot.

I didn't realise bio students were even aware of the existence of numbers.

Re: HSC 2015 3U Marathon If not having a +c is "faulty", then the table of standard integrals on the back of every HSC exam is also "faulty".

Re: Year 11 Mathematics 3 Unit Cambridge Question & Answer Thread We don't need triple angle formulae for this: 3x = x + 2kπ 2x = 2kπ x = kπ OR 3x = (2π - x) + 2kπ 4x = 2(k+1)π x = (k+1)π/2 which is identical to: x = kπ/2 This answer includes all answers from the first solution. So the...

Re: Year 11 Mathematics 3 Unit Cambridge Question & Answer Thread Why don't you combine those last 2 answers into just x = nπ

Re: Year 11 Mathematics 3 Unit Cambridge Question & Answer Thread When you multiply through by (1-t²) (1+t²), you can't get a t^6 term.

Look your school up here to see how many E4s they have got in maths in recent years: http://topscores.info/select-nsw.php#pagehere

Re: Year 11 Mathematics 3 Unit Cambridge Question & Answer Thread I meant multiply after applying the t-results.

As I said in an earlier post, the answer cannot possibly be as high as 72.

Re: MX2 2015 Integration Marathon When I try it on Wolfram, it just repeats the question as the answer, and draws the region. It is not telling me anything about convergence.

Re: Year 11 Mathematics 3 Unit Cambridge Question & Answer Thread Once you multiply to remove fractions then simplify, it is actually very uncomplicated. The only trick is at the last step.

Re: MX2 2015 Integration Marathon So nobody is concerned that ln[sin(0)] does not exist?

Re: MX2 2015 Integration Marathon In an exam, you can't quote integrals that are not on the standard integrals sheet.
