How do I prove $\frac{\mathrm{sin}x+\mathrm{csc}y}{\mathrm{sin}y+\mathrm{csc}x}=\mathrm{csc}y\mathrm{sin}x$ ?

Find range of the function

$f\left(x\right)=3\left|\mathrm{sin}x\right|-4\left|\mathrm{cos}x\right|$

I tried to do by using the trigonometric identities

$\mathrm{sin}}^{2}x=\frac{1-\mathrm{cos}2x}{2};\text{}\text{}{\mathrm{cos}}^{2}x=\frac{1+\mathrm{cos}2x}{2$

So

$f\left(x\right)=3\sqrt{\frac{1-\mathrm{cos}2x}{2}}-4\sqrt{\frac{1+\mathrm{cos}2x}{2}}$

but don't know how to proceed from here
