derivative of

\frac{s ^{3} x}{cos ( x )}

3 s^{2} x sec (x)

Solution steps

\frac{d}{d s} (\frac{s ^{3} x}{cos ( x )})

Simplify

\frac{s ^{3} x}{cos ( x )} : s^{3} x sec (x)

= \frac{d}{d s} (s^{3} x sec (x))

Treat

x

as a constant

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= x sec (x) \frac{d}{d s} (s^{3})

Apply the Power Rule:

\frac{d}{d x} (x^{a}) = a \cdot x^{a - 1}

= x sec (x) \cdot 3 s^{3 - 1}

Simplify

= 3 s^{2} x sec (x)

\frac{d}{d a} (cos^{2} (a) + sec^{2} (a))

\frac{d}{d s} (\frac{( s ^{2} - a ^{2} )}{( s ^{2} + s ^{2} ) ^{2}})

\frac{d}{d t} (- 20 + 5 t)

y = \frac{1 + x + x ^{2}}{1 - x ^{2}}

\frac{( x ^{4} - 5 )}{( x ^{2} + 3 )}
