integral of (2-1/x)ln(x)

\int (2 - \frac{1}{x}) ln (x) d x

2 (x ln (x) - x) - \frac{ln ^{2} ( x )}{2} + C

Solution steps

\int (2 - \frac{1}{x}) ln (x) d x

Expand

(2 - \frac{1}{x}) ln (x) : 2 ln (x) - \frac{ln ( x )}{x}

= \int 2 ln (x) - \frac{ln ( x )}{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 2 ln (x) d x - \int \frac{ln ( x )}{x} d x

\int 2 ln (x) d x = 2 (x ln (x) - x)

\int \frac{ln ( x )}{x} d x = \frac{ln ^{2} ( x )}{2}

= 2 (x ln (x) - x) - \frac{ln ^{2} ( x )}{2}

Add a constant to the solution

= 2 (x ln (x) - x) - \frac{ln ^{2} ( x )}{2} + C

\frac{d}{d x} (10 sin (x) + 103 cos (x))

y = 9 x - 6 x, (1, 3)

x \to 1 lim (x^{4} - 1)

\int \frac{x ^{5} - x ^{4} + 4 x ^{2} - x}{x ^{3} + 1} d x

x \to 0 lim (x cos (\frac{7}{x}))
