Solve the separable differential equation {eq}\displaystyle 10 x - 6 y \sqrt {x^2 + 1}\ \dfrac {dy}{dx} = 0 {/eq}, with the initial condition {eq}y(0) = 4 {/eq}.

Solution of the Differential Equation:

The given differential equation can be solved by separating the equation into two parts. We move all of the equations involving the {eq}y{/eq} variable to one side and all of the equation involving the {eq}x{/eq} variable to the other side, then we can integrate both sides.

$$\displaystyle\int P(y)\: dy=\int Q(x)\: dx $$

Consider the differential equation

$$\displaystyle 10 x - 6 y \sqrt {x^2 + 1}\ \dfrac {dy}{dx} = 0,\quad y(0)=4\\ \displaystyle 6 y \sqrt {x^2 + 1}\...
