\frac{d}{d x} (3 cosh (2 x))

6 sinh (2 x)

Solution steps

\frac{d}{d x} (3 cosh (2 x))

Take the constant out:

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

= 3 \frac{d}{d x} (cosh (2 x))

Apply the chain rule:

sinh (2 x) \frac{d}{d x} (2 x)

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

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

= 3 sinh (2 x) \cdot 2

Simplify

= 6 sinh (2 x)

\int \frac{6 x ^{2} + 7 x - 6}{( x ^{2} - 4 ) ( x + 2 )} d x

x \to 1 lim ([2 x])

\frac{d}{d x} (5 sin (x) + x cos (x))

\frac{d ^{2} S}{d x ^{2}} = x

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