\frac{d}{d x} (- 2 tan (x))

- 2 sec^{2} (x)

Solution steps

\frac{d}{d x} (- 2 tan (x))

Take the constant out:

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

= - 2 \frac{d}{d x} (tan (x))

Apply the common derivative:

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

= - 2 sec^{2} (x)

\int (4 x - 1)^{3} d x

\int_{1}^{6} (2 x^{3} + 5 x^{2} + 2 x + 8) d x

x \to 3 + lim (\frac{1}{6 - 2 x})

f (x) = 1.1 x + e^{x}, at x = 0

\int \frac{x ^{2}}{x ^{4} - 6 x ^{2} - 27} d x
