Find $f^{\prime }(x)$ if $f(x)=\frac{x^3-\sqrt[4]{x^3}}{2x}$

Use the quotient rule of $\frac{d}{dx}\frac{f(x)}{g(x)}=\frac{f^{\prime }(x)g(x)-f(x)g^{\prime }(x)}{(g(x){)}^2}$

---

Find $h^{\prime }(x)$ if $h\left(x\right)=\left(2\csc x\right)\left(5\sin x-3x\right)$

Use the product rule of $\frac{d}{dx}f(x)g(x)=f^{\prime }(x)g(x)+f(x)g^{\prime }(x)$
