• fan96 replied to the thread Hard Proofs Question.
I think there's a possibility that there's some algebraic trick you can do (independent of the previous parts) to find C once you know...
• fan96 replied to the thread Inequalities question help.
Hint: Make the substitutions a = e^\alpha, b = e^\beta, c = e^\gamma.
• If you plot this using software the graph you get is not the same as the original parametric equation. (You only get the upper half of...
• Observe that x + y = 9 \cos \theta 5x - 4y = -9 \sin \theta so \left(x+y\right)^2+\left(5x-4y\right)^2=81.
• fan96 replied to the thread discrete mathematics.
Are we talking about the UNSW course? If so then I didn't really like it. Out of the seven math courses I've done so far I'd rank this...
• fan96 replied to the thread Polynomial question help!!.
That isn't quite what I said - I said if a,b,c were constants then the expression is a polynomial. What sort of polynomial it is, we...
• fan96 replied to the thread Polynomial question help!!.
The question introduced (a-2)x^2+(1-3b)x+(5-2c) as simply a polynomial (which it is, if we assume a, b, c are constants). It never...
• fan96 replied to the thread Linear Algebra.
"Linear Algebra" is a massive field of study, so a comprehensive formula sheet would be at least the size of a textbook. You would have...
