derivative of x^2-xy=7

\frac{d}{d x} (x^{2} - x y) = 7

y = - 7 - \frac{c _{1}}{x} + x

Solution steps

\frac{d}{d x} (x^{2} - x y) = 7

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

then

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

x^{2} - x y = \int 7 d x

\int 7 d x = 7 x + c_{1}

x^{2} - x y = 7 x + c_{1}

Isolate

y : y = - 7 - \frac{c _{1}}{x} + x

y = - 7 - \frac{c _{1}}{x} + x

\frac{d}{d x} (- \frac{1}{1 + y ^{2}} - cos (x) + 2 x y)

\frac{x}{9 + x}

x \to 1 lim (\frac{x - 1}{1 - x ^{2}})

\int x^{4} sin (2 x) d x

f (x) = arcsin (6 x^{4})
