integral of 1/(xsqrt(1+ln(x^2)))

\int \frac{1}{x 1 + ln ( x ^{2} )} d x

1 + 2 ln (x) + C

Solution steps

\int \frac{1}{x 1 + ln ( x ^{2} )} d x

Apply u-substitution

: \int \frac{1}{2 u} d u

= \int \frac{1}{2 u} d u

Take the constant out:

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

= \frac{1}{2} \cdot \int \frac{1}{u} d u

Apply the Power Rule

: 2 u^{\frac{1}{2}}

= \frac{1}{2} \cdot 2 u^{\frac{1}{2}}

Substitute back

u = 1 + ln (x^{2})

= \frac{1}{2} \cdot 2 (1 + ln (x^{2}))^{\frac{1}{2}}

Simplify

\frac{1}{2} \cdot 2 (1 + ln (x^{2}))^{\frac{1}{2}} : 1 + 2 ln (x)

= 1 + 2 ln (x)

Add a constant to the solution

= 1 + 2 ln (x) + C

\frac{\partial}{\partial x} (25 - x^{2} - 5 y)

\frac{d}{d x} (sin (2 π))

n = 0 \sum \infty \frac{5}{π ^{n}}

(4 x^{3})^{^{'}}

\frac{d}{d x} (4 + 2 x - 3 x^{2} - 5 x^{3} - 8 x^{4} + 9 x^{5})
