integral from 3 to 11 of 1/(sqrt(2x+3))

\int_{3}^{11} \frac{1}{2 x + 3} d x

2

Solution steps

\int_{3}^{11} \frac{1}{2 x + 3} d x

Apply u-substitution

: \int_{9}^{25} \frac{1}{2 u} d u

= \int_{9}^{25} \frac{1}{2 u} d u

Take the constant out:

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

= \frac{1}{2} \cdot \int_{9}^{25} \frac{1}{u} d u

Apply the Power Rule

: [2 u^{\frac{1}{2}}]_{9}^{25}

= \frac{1}{2} [2 u^{\frac{1}{2}}]_{9}^{25}

Apply radical rule:

a^{\frac{1}{n}} = n a

= \frac{1}{2} [2 u]_{9}^{25}

Compute the boundaries:

4

= \frac{1}{2} \cdot 4

Simplify

= 2

x^{\frac{9}{6}}

f (x) = - 10 x^{2} + 1760 x - 50000

f (t) = 9 t - 2 t^{2}

y^{^{''}} - 2 y^{^{'}} + y = 3 e^{t} cos (t)

x \to 0 lim (\frac{1}{1 - x})
