integral from sqrt(y) to 1 of cos(x^3)

\int_{y}^{1} cos (x^{3}) d x

- \frac{1 \cdot ( 3 i 1 ^{3} Γ ( \frac{1}{3} , - i 1 ^{3} ) + 3 - i 1 ^{3} Γ ( \frac{1}{3} , i 1 ^{3} ) )}{6 3 1 ^{6}} - - \frac{y ( 3 i ( y ) ^{3} Γ ( \frac{1}{3} , - i ( y ) ^{3} ) + 3 - i ( y ) ^{3} Γ ( \frac{1}{3} , i ( y ) ^{3} ) )}{6 3 ( y ) ^{6}}

Solution steps

\int_{y}^{1} cos (x^{3}) d x

Use the nonelementary integral:

\int cos (x^{3}) d x = - \frac{x ( 3 i x ^{3} Γ ( \frac{1}{3} , - i x ^{3} ) + 3 - i x ^{3} Γ ( \frac{1}{3} , i x ^{3} ) )}{6 3 x ^{6}}

= [- \frac{x ( 3 i x ^{3} Γ ( \frac{1}{3} , - i x ^{3} ) + 3 - i x ^{3} Γ ( \frac{1}{3} , i x ^{3} ) )}{6 3 x ^{6}}]_{y}^{1}

Compute the boundaries:

- \frac{1 \cdot ( 3 i 1 ^{3} Γ ( \frac{1}{3} , - i 1 ^{3} ) + 3 - i 1 ^{3} Γ ( \frac{1}{3} , i 1 ^{3} ) )}{6 3 1 ^{6}} - - \frac{y ( 3 i ( y ) ^{3} Γ ( \frac{1}{3} , - i ( y ) ^{3} ) + 3 - i ( y ) ^{3} Γ ( \frac{1}{3} , i ( y ) ^{3} ) )}{6 3 ( y ) ^{6}}

= - \frac{1 \cdot ( 3 i 1 ^{3} Γ ( \frac{1}{3} , - i 1 ^{3} ) + 3 - i 1 ^{3} Γ ( \frac{1}{3} , i 1 ^{3} ) )}{6 3 1 ^{6}} - - \frac{y ( 3 i ( y ) ^{3} Γ ( \frac{1}{3} , - i ( y ) ^{3} ) + 3 - i ( y ) ^{3} Γ ( \frac{1}{3} , i ( y ) ^{3} ) )}{6 3 ( y ) ^{6}}

\int_{1}^{5} (- x^{2} + 3 x + 2) d x

\int_{5}^{6} 1 d x

\int_{0}^{0.1} e^{- x^{2}} d x

\int_{0}^{π} (8 e^{x} + 8 sin (x)) d x

\int_{- 7}^{7} \frac{x ^{3}}{11 + 8 x ^{2}} d x
