integral from-1 to 1 of (cos(x))/(1+x^4)

\int_{- 1}^{1} \frac{cos ( x )}{1 + x ^{4}} d x

1.50103 \dots

Solution steps

\int_{- 1}^{1} \frac{cos ( x )}{1 + x ^{4}} d x

Evaluating using numerical calculation methods

= 1.50103 \dots

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

\int_{0}^{π} 3 d x

\int_{1}^{0} ln (x) d x

\int_{1}^{4} \frac{1}{( x - 2 ) ^{\frac{3}{2}}} d x

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