What are the other differences between this and the fx-82? Is it just being able to do arithmetic with complex numbers and the normal...

Yep. That's the problem when you prescribe and assess the same texts year after year. If you truly want to, you'll be able to find a way.
• fan96 replied to the thread English.
Although I really hated HSC English (because it compulsorily counted towards the ATAR and most of it was not useful), I found the...

Have anyone figured out? The trick is...
• Admittedly, I went through a lengthy process (including looking up a standard integral table for \text{sech} ) and it was only at the...
• 4. \int_0^\infty \frac{x^2}{x^6+1}\,dx = \frac 13 \int_{0}^\infty \frac{1}{u^2+1}\,du \quad (u = x^3) = \frac 13 \cdot \frac \pi 2 =...
• I have a feeling this is not the fastest method... I = \int_0^1\left( \arcsin\left(\frac{x}{x+1}\right)\right)^2\,dx =\int_0^{\pi/6}...
• For UNSW there is a difference between Adv Sci (Mathematics) and Adv Math, at least in terms of program structure. For example...
• It's whichever one you're personally interested in more. Scaling is nice, but if you don't enjoy the subject then you'll need to put in...
• If one of them is clearly more convenient, then pick that one. For example, if we have the system \begin{cases} 2x+7y &= 4 \\ 4x +...
• A system of simultaneous equations is just a set of conditions. When we solve a system like this, we're simply finding and using...
• Your answer doesn't work for the second equation: 3(3)-(-2) = 9 + 2 = 11 \neq 7.
• \frac{1+\sqrt{1+\frac{\sqrt{3}}2}}{\sqrt{1+\frac{\sqrt{3}}2}} \cdot \frac 22 = \frac{2+\sqrt{4+2\sqrt3}}{\sqrt{4+2\sqrt3}} = \frac{3 +...

• ii) The line through AP has equation y = t(x+1) . (can you see why?) Solve this simultaneously with the equation for the unit circle...
