derivative of x-9

derivative of

x - 9

1

Solution steps

\frac{d}{d x} (x - 9)

Apply the Sum/Difference Rule:

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

= \frac{d x}{d x} - \frac{d}{d x} (9)

\frac{d x}{d x} = 1

\frac{d}{d x} (9) = 0

= 1 - 0

Simplify

= 1

\int \frac{1}{2 x ^{2} + 4 x + 7} d x

\frac{1}{6} y^{^{''}} + 6 y = 4 tan (6 t) - \frac{1}{2} e^{3 t}

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

\frac{\partial}{\partial x} (x ln (x + 6 y))

y^{^{''}} - 5 y^{^{'}} = e^{5 x}
