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

2 x - 2 \frac{d y}{d x}

Solution steps

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

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

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

\frac{d}{d x} (x^{2}) = 2 x

\frac{d}{d x} (2 y) = 2 \frac{d y}{d x}

= 2 x - 2 \frac{d y}{d x}

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

\frac{d}{d x} (\frac{1}{2 x + 8})

y^{^{''}} - 8 y^{^{'}} + 15 y = 2 e^{3 x}

e^{x}, x e^{x}, [0, 1]

\frac{\partial}{\partial x} (a ln (x) + b ln (y))
