Re: general UNSW chit-chat Bean bags in the library? Dayum

Haha well done.

Thanks Lol I forgot to do them, I did have \pm k \pi though:p

$It's for all integers, unless bounded. Say for example we have a question, what is $ sin^{-1}0 $Well there are an infinite number of solutions, so we write it as $ \pm k \pi, k \in \mathbb{Z}. $That means the solutions are $ 0, \pm\pi, \pm2\pi, \pm3\pi, \pm4\pi $ etc etc$

a is a real number which means a^2 must be positive as if a^2 is negative then a would be nonreal

yep

Physics is barely maths based lol, too much nonmaths in it :(

This I never used maths online, they didn't have 4unit stuff so I disliked it :cry: And I preferred using textbooks and such.

2.1 Q5 $For the first one, you have $ w^3 = 1 w^3 - 1=0 (w-1)(w^2 + w +1)=0 $Solve the quadratic to give you the roots, same with w^3 = -1$ 2.2 Q11 $Next one, Let $ a +bi = \sqrt{5 + 2i} a^2 - b^2 + 2abi = 5 + 2i $Equating real and imaginary parts, $ 2ab = 2 a = \frac{1}{b}, b =...
