integral from 1 to 4 of x^2+1/(4x^2)

\int_{1}^{4} x^{2} + \frac{1}{4 x ^{2}} d x

\frac{339}{16}

Decimal Notation

21.1875

Solution steps

\int_{1}^{4} x^{2} + \frac{1}{4 x ^{2}} d x

Apply the Sum Rule:

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

= \int_{1}^{4} x^{2} d x + \int_{1}^{4} \frac{1}{4 x ^{2}} d x

\int_{1}^{4} x^{2} d x = 21

\int_{1}^{4} \frac{1}{4 x ^{2}} d x = \frac{3}{16}

= 21 + \frac{3}{16}

Simplify

21 + \frac{3}{16} : \frac{339}{16}

= \frac{339}{16}

\int \frac{e ^{x}}{a + b e ^{x}} d x

(3 + x^{2}) y^{^{'}} - 2 x y = 0

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

\int (2 x^{3} - x^{2} + 3 x - 7) d x

\int_{0}^{2} 5 d x
