Mathematics

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac16x(1-y^2)$
$\displaystyle\int\frac{\mathrm dy}{1-y^2}=\frac16\int x\,\mathrm dx$
$\dfrac12\ln|1+y|-\dfrac12\ln|1-y|=\dfrac1{12}x^2+C$
$\ln\left|\dfrac{1+y}{1-y}\right|=\dfrac16x^2+C$
$\dfrac{1+y}{1-y}=e^{x^2/6+C}$
$-1+\dfrac2{1-y}=Ce^{x^2/6}$
$y=1-\dfrac2{1+Ce^{x^2/6}}$

Given that y(0)=7

, we get

$7=1-\dfrac2{1+Ce^0}\implies C=-\dfrac43$

so the particular solution is

$y=1-\dfrac2{1-\frac43e^{x^2/6}}$
