Lines `L_(1)= ax+by+c=0 and L_(2) -= lx+ mu+n=0` intersect at the point P and makes an angle `theta` with each other. Find the eqauation of a line L different from `L_(2)` which passes through P and makes the same angle `theta` with `L_(1)`.

Text Solution

Verified by Experts

The correct Answer is:
`L_(2)(a^(2)+b^(2)) and-2(al+bm)L_(1)=0`
