sqrt(1-9x^2)y^'=x

1 - 9 x^{2} y^{^{'}} = x

y = - \frac{1}{9} 1 - 9 x^{2} + c_{1}

Solution steps

1 - 9 x^{2} y^{'} (x) = x

Isolate

y^{'} (x) : y^{'} (x) = \frac{x}{1 - 9 x ^{2}}

f^{^{'}} (x) = g (x)

then

f (x) = \int g (x) d x

y = \int \frac{x}{1 - 9 x ^{2}} d x

\int \frac{x}{1 - 9 x ^{2}} d x = - \frac{1}{9} 1 - 9 x^{2} + c_{1}

y = - \frac{1}{9} 1 - 9 x^{2} + c_{1}
