\frac{d}{d x} (20 x^{\frac{1}{2}} - \frac{1}{2} x^{20})

\frac{10 - 10 x ^{\frac{39}{2}}}{x ^{\frac{1}{2}}}

Solution steps

\frac{d}{d x} (20 x^{\frac{1}{2}} - \frac{1}{2} x^{20})

Simplify

20 x^{\frac{1}{2}} - \frac{1}{2} x^{20} : 20 x^{\frac{1}{2}} - \frac{x ^{20}}{2}

= \frac{d}{d x} (20 x^{\frac{1}{2}} - \frac{x ^{20}}{2})

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d}{d x} (20 x^{\frac{1}{2}}) - \frac{d}{d x} (\frac{x ^{20}}{2})

\frac{d}{d x} (20 x^{\frac{1}{2}}) = \frac{10}{x ^{\frac{1}{2}}}

\frac{d}{d x} (\frac{x ^{20}}{2}) = 10 x^{19}

= \frac{10}{x ^{\frac{1}{2}}} - 10 x^{19}

Simplify

\frac{10}{x ^{\frac{1}{2}}} - 10 x^{19} : \frac{10 - 10 x ^{\frac{39}{2}}}{x ^{\frac{1}{2}}}

= \frac{10 - 10 x ^{\frac{39}{2}}}{x ^{\frac{1}{2}}}

\int \frac{sin ^{7} ( 6 x )}{cos ^{4} ( 6 x )} d x

x \to 2.9 lim (x^{2} + 3 x)

y = \frac{2 t}{3 + t ^{2}}

x \to - 1 lim (x^{2} + 1)

\frac{\partial}{\partial y} (e^{x y} x)
