integral of sqrt(2)xln(4x)

\int 2 \cdot x \cdot ln (4 x) d x

2 (\frac{1}{2} x^{2} ln (4 x) - \frac{x ^{2}}{4}) + C

Solution steps

\int 2 x ln (4 x) d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 2 \cdot \int x ln (4 x) d x

Apply Integration By Parts

: \frac{1}{2} x^{2} ln (4 x) - \int \frac{x}{2} d x

= 2 (\frac{1}{2} x^{2} ln (4 x) - \int \frac{x}{2} d x)

\int \frac{x}{2} d x = \frac{x ^{2}}{4}

= 2 (\frac{1}{2} x^{2} ln (4 x) - \frac{x ^{2}}{4})

Add a constant to the solution

= 2 (\frac{1}{2} x^{2} ln (4 x) - \frac{x ^{2}}{4}) + C

\int y x d x

\int_{0}^{π} sin^{2} (t co) s^{4} t d t

\frac{d y}{d t} = 0.225 - \frac{y}{200}, y (0) = 90

(x^{2} + 1) \cdot e^{x - 1}

t + 2
