SOLUTION

<P>

TO SOLVE

The differential equation

\sf{y = xp +  \sqrt{1 +  {p}^{2} } }

EVALUATION

Here the given differential equation is

\sf{y = xp +  \sqrt{1 +  {p}^{2} } }

This equation is of the form

\sf{y = xp +  f(p) }

Which is Clairaut's equation

Now for Clairaut's equation the general solution is obtained replacing p by C

Hence the required solution is

\sf{y = cx+  \sqrt{1 +  {c}^{2} } }

Where C is constant
