Lines L1-=a x+b y+c=0 and L2-=l x+m y+n=...

Lines `L_1-=a x+b y+c=0` and `L_2-=l x+m y+n=0` intersect at the point `P` and make an angle `theta` with each other. Find the equation of a line different from `L_2` which passes through `P` and makes the same angle `theta` with `L_1dot`

Text Solution

Verified by Experts

The correct Answer is:
`a(al+bm)(ax+by+c)-(a^(2)+b^(2))(1x+my+n)=0`
