Simplify $x^{11}\cos\left(x\right)\sin\left(x\right)\ln\left(x\right)$ using the trigonometric identity: $\sin(2x)=2\sin(x)\cos(x)$

Multiplying the fraction by $x^{11}\ln\left(x\right)$

Divide fractions $\frac{\frac{x^{11}\sin\left(2x\right)\ln\left(x\right)}{2}}{e^x\sqrt{x+5}}$ with Keep, Change, Flip: $\frac{a}{b}\div c=\frac{a}{b}\div\frac{c}{1}=\frac{a}{b}\times\frac{1}{c}=\frac{a}{b\cdot c}$
