A) \[\lambda =h\]
B) \[\lambda =g\]
C) \[\lambda =fg\]
D) \[\lambda \]may have any value
Correct Answer: D
Solution :
Making the equation of curve homogeneous with the help of equation of line \[\frac{fx-gy}{\lambda }=1\]and to be perpendicular to both the lines represented by this homogeneous equation \[a+b=0\Rightarrow \lambda +gf-\lambda -gf=0\Rightarrow 0=0\] Hence, \[\lambda \]may have any value.You need to login to perform this action.
