integral from 2 to 3 of (27)/(sqrt(3-x))

\int_{2}^{3} \frac{27}{3 - x} d x

54

Solution steps

\int_{2}^{3} \frac{27}{3 - x} d x

Take the constant out:

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

= 27 \cdot \int_{2}^{3} \frac{1}{3 - x} d x

Apply u-substitution

: \int_{1}^{0} - \frac{1}{u} d u

= 27 \cdot \int_{1}^{0} - \frac{1}{u} d u

\int_{a}^{b} f (x) d x = - \int_{b}^{a} f (x) d x, a < b

= 27 (- \int_{0}^{1} - \frac{1}{u} d u)

Take the constant out:

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

= 27 (- (- \int_{0}^{1} \frac{1}{u} d u))

Apply the Power Rule

: [2 u^{\frac{1}{2}}]_{0}^{1}

= 27 (- (- [2 u^{\frac{1}{2}}]_{0}^{1}))

Simplify

27 (- (- [2 u^{\frac{1}{2}}]_{0}^{1})) : 27 [2 u]_{0}^{1}

= 27 [2 u]_{0}^{1}

Compute the boundaries:

2

= 27 \cdot 2

Simplify

= 54

\int \frac{5 e ^{x}}{e ^{x} + 4} d x

x \to 8 - lim (\frac{6 x}{x - 8})

f (t) = t^{2} + 1

\frac{\partial}{\partial t} (s^{2} t)

n = 2 \sum \infty e^{3 - 6 n}
