\int_{1}^{3} 3^{4 x} d x

Vereinfache

3^{4 x} : 8 1^{x}

= \int_{1}^{3} 8 1^{x} d x

\int a^{x} d x = \frac{a ^{x}}{ln a}

= [\frac{8 1 ^{x}}{ln ( 81 )}]_{1}^{3}

Vereinfache

ln (81) : 4 ln (3)

= [\frac{8 1 ^{x}}{4 ln ( 3 )}]_{1}^{3}

\int_{1}^{4} \frac{ln ( x )}{x} d x

\int_{0}^{\frac{π}{2}} 2 x cos (x) d x

\int_{- 1}^{0} x^{2} x^{3} + 1 d x

\int_{0}^{\frac{π}{6}} sin^{3} (x) d x

\int_{- 2}^{1} x^{4} + x^{3} - 2 x^{2} + 4 d x
