integral from 0 to 1 of (e^x+e^{-x})

\int_{0}^{1} (e^{x} + e^{- x}) d x

\frac{e ^{2} - 1}{e}

Solution steps

\int_{0}^{1} e^{x} + e^{- x} d x

Rewrite using trig identities

= \int_{0}^{1} 2 cosh (x) d x

Take the constant out:

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

= 2 \cdot \int_{0}^{1} cosh (x) d x

Use the common integral:

\int cosh (x) d x = sinh (x)

= 2 [sinh (x)]_{0}^{1}

Compute the boundaries:

\frac{e ^{2} - 1}{2 e}

= 2 \cdot \frac{e ^{2} - 1}{2 e}

Simplify

= \frac{e ^{2} - 1}{e}

\frac{d}{d x} (100 (5.6)^{x})

f (x) = \frac{7}{x + 4}

\int 1.1 t + 6.3 t^{3} d t

s (t) = 48 (6 t^{3} - 5)^{\frac{6}{5}}

e^{x} (5 x^{2} - 10 x + 10)
