\int_{1}^{e} \frac{1}{t} d t

1

Solution steps

\int_{1}^{e} \frac{1}{t} d t

Use the common integral:

\int \frac{1}{t} d t = ln (∣ t ∣)

= [ln ∣ t ∣]_{1}^{e}

Compute the boundaries:

1

= 1

\int_{0}^{7} \frac{x}{x ^{2} + 15} d x

\int_{0}^{4} e^{2 x + 1} d x

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

\int_{0}^{2} 7 d x

\int_{0}^{1} x 2^{x} d x
