integral of (3/(sqrt(x))+3sqrt(x))

\int (\frac{3}{x} + 3 x) d x

6 x + 2 x^{\frac{3}{2}} + C

Solution steps

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

\int \frac{3}{x} d x = 6 x

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

= 6 x + 2 x^{\frac{3}{2}}

Add a constant to the solution

= 6 x + 2 x^{\frac{3}{2}} + C

\frac{d}{d x} (x (cos (x)))

9 x^{2} - 1

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

y = cos^{4} (t) - sin^{4} (t)

\frac{\partial}{\partial x} (- \frac{7 x ^{2}}{x ^{2} + y ^{2}})
