integral of (e^{sqrt(x)}-3)/(sqrt(x))

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

2 (e^{x} - 3 x) + C

Solution steps

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

Apply u-substitution

: \int 2 (e^{u} - 3) d u

= \int 2 (e^{u} - 3) d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 2 \cdot \int e^{u} - 3 d u

Apply the Sum Rule:

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

= 2 (\int e^{u} d u - \int 3 d u)

\int e^{u} d u = e^{u}

\int 3 d u = 3 u

= 2 (e^{u} - 3 u)

Substitute back

u = x

= 2 (e^{x} - 3 x)

Add a constant to the solution

= 2 (e^{x} - 3 x) + C

x \to 1 lim (2 x^{2} - 3 x + 4)

\frac{d}{d x} (x^{\frac{1}{11}})

y = - 3 cos (x), at x = \frac{3}{4} π

f (x) = \frac{e ^{- 2 x}}{x}

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