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

9 sec^{2} (x)

Solution steps

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

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

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

Apply the common derivative:

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

= 9 sec^{2} (x)

\frac{\partial}{\partial x} (\frac{10 x}{1 + x ^{2} - y})

\frac{\partial}{\partial y} (\frac{y}{2})

f (x) = 3 x^{2} - 1

\frac{d y}{d x} = x + 6 y, y (0) = 2

f (x) = \frac{4 x + 5}{x - 1}, (2, 13)
