A) \[y-\sqrt{{{x}^{2}}+{{y}^{2}}}=c{{x}^{2}}\]
B) \[y+\sqrt{{{x}^{2}}+{{y}^{2}}}=c{{x}^{2}}\]
C) \[y+\sqrt{{{x}^{2}}+{{y}^{2}}}+c{{x}^{2}}=0\]
D) None of these
Correct Answer: B
Solution :
It is a homogenous equation, solve it by putting \[y=vx\]and \[\frac{dy}{dx}=v+x\frac{dv}{dx}\].You need to login to perform this action.
