integral of 1/4 e^{sqrt(x-1)}

\int \frac{1}{4} e^{x - 1} d x

\frac{1}{2} (e^{x - 1} x - 1 - e^{x - 1}) + C

Solution steps

\int \frac{1}{4} e^{x - 1} d x

Take the constant out:

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

= \frac{1}{4} \cdot \int e^{x - 1} d x

Apply u-substitution

: \int e^{u} \cdot 2 u d u

= \frac{1}{4} \cdot \int e^{u} \cdot 2 u d u

Take the constant out:

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

= \frac{1}{4} \cdot 2 \cdot \int e^{u} u d u

Apply Integration By Parts

: e^{u} u - \int e^{u} d u

= \frac{1}{4} \cdot 2 (e^{u} u - \int e^{u} d u)

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

= \frac{1}{4} \cdot 2 (e^{u} u - e^{u})

Substitute back

u = x - 1

= \frac{1}{4} \cdot 2 (e^{x - 1} x - 1 - e^{x - 1})

Simplify

\frac{1}{4} \cdot 2 (e^{x - 1} x - 1 - e^{x - 1}) : \frac{1}{2} (e^{x - 1} x - 1 - e^{x - 1})

= \frac{1}{2} (e^{x - 1} x - 1 - e^{x - 1})

Add a constant to the solution

= \frac{1}{2} (e^{x - 1} x - 1 - e^{x - 1}) + C

\frac{\partial}{\partial y} (sin (2 x - y))

\int (1 + e^{- a t})^{\frac{3}{2}} e^{- a t} d t

3 e^{x} + \frac{4}{3 x}

y = (\frac{1}{2 x + 1})^{2}

x \to a lim ((1 + \frac{1}{x})^{x})
