\frac{d}{d x} (1 + cos (3 π x))

- 3 π sin (3 π x)

Solution steps

\frac{d}{d x} (1 + cos (3 π x))

Apply the Sum/Difference Rule:

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

= \frac{d}{d x} (1) + \frac{d}{d x} (cos (3 π x))

\frac{d}{d x} (1) = 0

\frac{d}{d x} (cos (3 π x)) = - sin (3 π x) \cdot 3 π

= 0 - sin (3 π x) \cdot 3 π

Simplify

= - 3 π sin (3 π x)

\int \frac{1}{1 + cos ( u )} d u

\int ln (1 + y^{2}) d y

\int \frac{2}{x + 5} d x

\int \frac{1}{3 x ^{2} + 6 x + 7} d x

\int 3 x ln (x) d x
