# How do you differentiate f(x)= (x) / (csc(x)+8)?

f(x)=$\frac{\left(\csc x + 8\right) - x \left(- \csc x \cdot \cot x + 0\right)}{\csc + 8} ^ 2$
using quotient rule: $d \frac{\left(f \frac{x}{g} \left(x\right)\right)}{\mathrm{dx}} = \frac{g \left(x\right) \cdot d \frac{f \left(x\right)}{\mathrm{dx}} - f \left(x\right) \cdot d \frac{g \left(x\right)}{\mathrm{dx}}}{g \left(x\right)} ^ 2$
