Re: HSC 2013 4U Marathon

From what I got quickly, it's a hyperbola with horizontal asympote at y=0 and vertical asymptote at x=1. Gonna check though as it was a rough thing.

Guys please explain, how do you find the motivation to actually write all this stuff up in laTex? I honestly see it and cant believe you guys write so much, doesnt it take up a shitload of time?? putting it into the laTex format?

Re: HSC 2013 4U Marathon

if you just blindly draw the reciprocal then it's wrong though
The only restriction that I can see is x > 0 which comes via default.

am I missing something?

If you learn latex then no it doesn't take much time at all.
If you are a fast typer, know latex well then the big blocks of latex I sometimes post don't take very long to write up.

LaTeX just comes with practice (and it really helps if you are fast typer).

It's the same curve I'm pretty sure.

x=/= 1 anyway on the x^y=e because if you convert it 1^y = e which is never possible. And also ln1 = 0 so y=1/0 undefined.

Re: HSC 2013 4U Marathon

If you are given parametric coordinates can you just ignore them and use the general tangent instead?
Make the equation of the general tangent a quadratic in terms of m then since they are perpendicular the product of roots = -1 and the locus is a circle with radius sqrt{a^2+b^2}.
