Find the equations of the lines which pass through the origin and are inclined at an angle `tan^(-1)m` to the line `y=mx+c dot`

Explanation

We know that the Angle between both the lines is
`tan^(−1)m pm tan^(−1)m=tan^(−1)(2m)/(1-m^2)` or `tan^(−1)0`

Therefore, the equations of the lines are `y=0,y=(2mx)/(1−m^2)`
