\frac{d}{d x} (b cos (x))

- b sin (x)

Solution steps

\frac{d}{d x} (b cos (x))

Take the constant out:

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

= b \frac{d}{d x} (cos (x))

Apply the common derivative:

\frac{d}{d x} (cos (x)) = - sin (x)

= b (- sin (x))

Simplify

= - b sin (x)

\int (cos^{4} (x) - sin^{4} (x)) d x

\int 6 t + 4 d t

\int_{3}^{6} t^{2} ln (2 t) d t

\int sec^{2} (x) + 2 d x
