integral of (xln(sin(x^2)))/(tan(x^2))

\int \frac{x ln ( sin ( x ^{2} ) )}{tan ( x ^{2} )} d x

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

Solution steps

\int \frac{x ln ( sin ( x ^{2} ) )}{tan ( x ^{2} )} d x

Apply u-substitution

: \int \frac{ln ( sin ( u ) )}{2 tan ( u )} d u

= \int \frac{ln ( sin ( u ) )}{2 tan ( 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{ln ( sin ( u ) )}{tan ( u )} d u

Rewrite using trig identities

= \frac{1}{2} \cdot \int ln (sin (u)) cot (u) d u

Apply u-substitution

: \int \frac{ln ( v )}{v} d v

= \frac{1}{2} \cdot \int \frac{ln ( v )}{v} d v

Apply u-substitution

: \int w d w

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

Apply the Power Rule

: \frac{w ^{2}}{2}

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

Substitute back

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

Simplify

\frac{1}{2} \cdot \frac{ln ^{2} ( sin ( x ^{2} ) )}{2} : \frac{1}{4} ln^{2} (sin (x^{2}))

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

Add a constant to the solution

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

\int \frac{x + 5}{2 - x} d x

\int \frac{sec ( x ) csc ( x )}{ln ( tan ( x ) )} d x

\int \frac{24 x ^{3}}{( x ^{4} - 5 ) ^{5}} d x

\int (3 x^{2} + 6 x - 2) (x^{3} + 3 x^{2} - 2 x + 5)^{4} d x

\int (4 x - 3) e^{- x} d x
