May 22	accepted	Solving for $x$ in a log equation
May 22	comment	Solving for $x$ in a log equation Oh... I was only looking for x-axis intersections from two equations for some reason. Weirdly enough, Wolfram Alpha doesn't give me the other solutions. Thanks!

May 1	comment	Proving identities using Pythagorean, Reciprocal and Quotient Ultimately used this method. Thanks for the guidance! Replacing the 1 with the cos and sin was something I never had todo before, so this knowledge definitely opens up some additional avenues in solving these. Thanks!

May 1	comment	Proving identities using Pythagorean, Reciprocal and Quotient Could you explain how the denominator of step 2 transforms to the squared cos subtracted by sin?

May 1	comment	Proving an identity using reciprocal, quotient, or Pythagorean identities. Oh I see, you are doing it a bit differently from Arturo which has mixed me up a bit. Thanks for this as well!

May 1	comment	Proving an identity using reciprocal, quotient, or Pythagorean identities. Oh! Convert $\csc$ and $\sec$ to the reciprocals, get $\frac{\sin^2 \theta}{\cos \theta \sin \theta}$, simplify and get $\tan\$! Thanks!
May 1	comment	Proving an identity using reciprocal, quotient, or Pythagorean identities. Oops, you are right. I understand this step as rationalizing the denominator, but I don't know how to proceed at all.
May 1	comment	Proving an identity using reciprocal, quotient, or Pythagorean identities. The LHS? I'm seriously at a lost here; another hint would be great.
May 1	comment	Proving an identity using reciprocal, quotient, or Pythagorean identities. $\frac{\tan \theta}{\sin^2 \theta}$? Is that correct?
May 1	comment	Proving an identity using reciprocal, quotient, or Pythagorean identities. It is equal to $1-\cos\theta$ or $\sin^2\theta$... still deciding what to do with it though.

Jan 29	comment	Which of the numbers $99^{100}$ and $100^{99}$ is the larger one? @Myself - Yep, wolframalpha.com/input/?i=999999%5E1000000+%3E+1000000%5E999999. Might have to give it a few seconds ;)
Nov 5	comment	Do online lecture recordings hurt or help math students at university? I love the point about seeing different lectures from different professors - different viewpoints can help you cement your knowledge and fill in any gaps you didn't know you even had!
Nov 2	accepted	Finding an inequality for a word problem
Nov 2	comment	Finding an inequality for a word problem Thank you! This does indeed help me see the problem as the linear inequalities we have been solving. I can pretty intuitively see that at around 27, 27 (which is around the right answer), the $x$ and $y$ values are about the same and then go to the point that rests on the boundary line. +1 for including the graphs, and because I might pick up R now ;)
