integral from 2x^2 to 1+x^2 of x+2y

\int_{2 x^{2}}^{1 + x^{2}} x + 2 y d y

x - x^{3} + 1 + 2 x^{2} - 3 x^{4}

Solution steps

\int_{2 x^{2}}^{1 + x^{2}} x + 2 y d y

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{2 x^{2}}^{1 + x^{2}} x d y + \int_{2 x^{2}}^{1 + x^{2}} 2 y d y

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

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

= x - x^{3} + 1 + 2 x^{2} - 3 x^{4}

\int_{3}^{9} x^{2} d x

\int_{1}^{6} t^{2} - 2 t - 15 d t

\int_{0}^{y} 2 z d z

\int_{0}^{1} 4^{5 x} d x

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