integral of (1/2 1/x+4sin(x))

\int (\frac{1}{2} \frac{1}{x} + 4 sin (x)) d x

\frac{1}{2} ln ∣ x ∣ - 4 cos (x) + C

Solution steps

\int \frac{1}{2} \cdot \frac{1}{x} + 4 sin (x) d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int \frac{1}{2} \cdot \frac{1}{x} d x + \int 4 sin (x) d x

\int \frac{1}{2} \cdot \frac{1}{x} d x = \frac{1}{2} ln ∣ x ∣

\int 4 sin (x) d x = - 4 cos (x)

= \frac{1}{2} ln ∣ x ∣ - 4 cos (x)

Add a constant to the solution

= \frac{1}{2} ln ∣ x ∣ - 4 cos (x) + C

\int (2 x e^{x}) d x

\int (1 + x^{3}) d x

\int \frac{sec ^{2} ( t )}{1 + 4 tan ^{2} ( t )} d t

\int cos (x) (1 + sin (x)) d x

\int (x^{4} - 8 x)^{2} (4 x^{3} - 8) d x
