integral from 1 to 2 of 3/x+5/(x^2)

\int_{1}^{2} \frac{3}{x} + \frac{5}{x ^{2}} d x

3 ln (2) + \frac{5}{2}

Decimal

4.57944 \dots

Solution steps

\int_{1}^{2} \frac{3}{x} + \frac{5}{x ^{2}} 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_{1}^{2} \frac{3}{x} d x + \int_{1}^{2} \frac{5}{x ^{2}} d x

\int_{1}^{2} \frac{3}{x} d x = 3 ln (2)

\int_{1}^{2} \frac{5}{x ^{2}} d x = \frac{5}{2}

= 3 ln (2) + \frac{5}{2}

x \to \infty lim ((lo g_{2} (x))^{2})

\frac{\partial}{\partial x} (y^{2} - 12 x)

\frac{d y}{d x}, 5 + 4 x = sin (x y^{3})

\int (\frac{1}{8}) y_{1} e^{- \frac{y _{1} + y _{2}}{2}} d y_{2}

f (x) = 3 x^{2}
