To all above attempting this question, learn to read properly. You are finding points of intersection of: y=\sqrt{4-x^2} and x-y+2=0 So (x+2)^2=4-x^2 \\ x^2+4x+4=4-x^2\\ x^2+2x=0 \\ x=0, -2\\y=2, 0

How many years ago did your friend mark papers? The epic scaling could be because the exams were a lot harder back then, and the syllabus has been dumbed down since 1980s. Nowadays any good 4 unit students should be able to get at least the majority of questions 1-6, while getting some of...

^Should be easy after the above substitution. Next question: \int sin(2x)ln(sinx) dx

area specified doesn't though, unless he meant to include the x axis.

lolwat?

You mean: \int \sqrt{\frac{x}{16-x}} dx

^ Don't need it. Just get course notes.

Re: which major should i choose from commerce for the course of Bcomce/Bscience(ad ma This as well.

Re: which major should i choose from commerce for the course of Bcomce/Bscience(ad ma Because you are essentially doing the same thing twice as most of the courses in each major overlap, while wasting one year in doing so.

[2(1)-\frac{1}{3}-1]-[2(-1)-\frac{(-1)^3}{3}-(-1)] = \frac{2}{3}-(-\frac{2}{3})=\frac{4}{3} thats what i got??

you mean \int_{-1}^{1} 2-(x^2+1) dx = [2x-\frac{x^3}{3}-x]_{-1}^{1} then you are correct.

diagram looks like the attachment. Area you want is in red. So answer is | \int_{-3}^{-2} -y^2-5y-6 dy|

For maths: prob ~$20 on course notes For finance: over $200 (will try to avoid) .... damn commerce courses

you need to be an exceptional student (extremely high ATAR) for the faculty to let you overload in your very first semester. Certain faculties are more flexible than others in terms of overloading.

Re: which major should i choose from commerce for the course of Bcomce/Bscience(ad ma \facepalm This is what we are suggesting you don't do. Either do finance in a single commerce degree OR quant risk in a single maths degree, but not both together. If you insist on doing finance in...

+1. High ATAR may not indicate intelligence and common sense, but low ATAR (<50) indicates stupidity

Re: which major should i choose from commerce for the course of Bcomce/Bscience(ad ma ^That, or alternately either do: - Quant risk alone in an advanced maths degree (You do most of the finance courses as you would in a finance major + you may learn some real maths in maths courses). The extra...

Correct! Explain how you got the answer.

Could you explain how you got these answers? Your answer is still not right.

Its not correct but I'm curious about how you got this answer.
