integral of (x^2-3/x+cos(x)-2/(sqrt(x)))

\int (x^{2} - \frac{3}{x} + cos (x) - \frac{2}{x}) d x

\frac{x ^{3}}{3} - 3 ln ∣ x ∣ + sin (x) - 4 x + C

Solution steps

\int x^{2} - \frac{3}{x} + cos (x) - \frac{2}{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 x^{2} d x - \int \frac{3}{x} d x + \int cos (x) d x - \int \frac{2}{x} d x

\int x^{2} d x = \frac{x ^{3}}{3}

\int \frac{3}{x} d x = 3 ln ∣ x ∣

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

\int \frac{2}{x} d x = 4 x

= \frac{x ^{3}}{3} - 3 ln ∣ x ∣ + sin (x) - 4 x

Add a constant to the solution

= \frac{x ^{3}}{3} - 3 ln ∣ x ∣ + sin (x) - 4 x + C

y = x^{2} - 7

\frac{\partial}{\partial y} (x cos (y) - y cos (x))

sin (t + c)

\int cos^{4} (\frac{x}{5}) d x

\int \frac{x + 3}{x ^{2} 2 x + 3} d x
