Angle bisector

I am having problems with angle bisetors in 2-D and 3-D. How do find the angle bisector for say 2x+3y=5 and 5x+6y=11 ?

Dude there are 2 ways.. the first way is to use the formula directly...

For finding angle bisectors, i wud say that doing that is the more correct/efficient way .. rather than trying to reinvent the wheel each time!

The genearl method to find the angle bisector is this:

y=mx+c
y=nn+d

eqth on line passign thru intersction is given by L1+kL2=0

we know tan theta1 and tan theta2

find tan (theta1+theta2)/2

equate the slope in the genreal eqtn to tan (theta1+theta2)/2

There is one thing that i din do... what is it?
