comment Solve the following differential equations by converting to Clairaut's form through suitable substitutions.
@Vish.Math See my last edit but be warned that there is never a satisfactory explanation for intuitive steps. Math is experience.

comment Black Scholes Merton PDE with a time variant boundary condition
A few questions: Is there a relationship between $r$, $\delta$ and $\sigma$? Are all constants positive? One bigger than the other, etc? What's the domain for $V$? What's the behavior you're expecting for $S$ as the price $V$ goes to infinity?

revised Is this function bounded? Next question about integral $\int_{\partial M} \frac{1}{||y-x||} n_y \cdot \nabla_y \frac1{||y-x||} dS_y$.

comment Solution of a differentiation in integral form
@ComplexGuy Nope, the definition of Spherical Bessel functions is \begin{align}j_n(x) &= \sqrt{\frac{\pi}{2 x}} J_{n + \frac{1}{2}}(x) \\ \\ y_n(x) &= \sqrt{\frac{\pi}{2 x}} Y_{n + \frac{1}{2}}(x)\end{align}

comment How to find out where a solution to a differential equation is defined?
The answer to your question is that theorem. Any ODE book will have a detailed proof, along with the relation between existence, uniqueness and continuation of solutions depending on parameters and initial conditions.

Have you read the Picard–Lindelöf theorem?
