What is that supposed to be?
I search Wikipedia, MathWorld, and Planetmath all results are negative.
G'day,
Firstly, i'd like to say hello to everyone, also, not to mention what a great service is being run here and how many people benefit from it.
I live in Australia and am in year 11.
I have been having problems understanding the auxilary method for some strange reason. Is there anyone that could maybe explain it to me, (and hope I understand it) or point me to a website?
Thanks,
Nick

What level of maths you doing? i've never heard of this auxilary method but it sounds like your talking about
Do you mean something like this:
Convert the coordinates (3, 4) to polar form:
1. Find distance using distance formula
2. Find the angle
EDIT: OK, I just saw the post above, i've never seen that method before, what does it do?
Ahhh, I found what your looking for in my 3 unit textbook. I sort of remmeber doing it, we didnt spend alot of time on it.
Its for solving trig equations, it some crazy method that didnt really make sense, so we didnt use it. But heres a question;
where and
Solve for
Solution:
Dividing both sides by
Since tan is positive in the first and forth quadrants:
How that has anything to do with this fancy equation solving thing I dunno? Thats probly why we never used it
