can someone please explain how i get from one step to another here?i dont understand the manipulation thats happened.
$\displaystyle \frac{1}{2} \mid log \frac{9.8}{2.1} \mid = \frac{1}{2} log36 $
i didnt want to waste time in latex lol, dont know how good your geometry skills are either:
1/2 ( $\displaystyle \mid $ log(72) $\displaystyle \mid $ = to the step i posted orginally, this probably wont make much more sense.
but the example question these workings are from is to find the hyperbolic distance between the points:
P= 3+3i and Q= -4 +4i (which will give an h-line |z+1|=5 ..to save time)
