\frac{d}{d x} (\frac{x ^{2}}{cos ( x )})

2 x sec (x) + sec (x) tan (x) x^{2}

Solution steps

\frac{d}{d x} (\frac{x ^{2}}{cos ( x )})

Simplify

\frac{x ^{2}}{cos ( x )} : x^{2} sec (x)

= \frac{d}{d x} (x^{2} sec (x))

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x^{2}, g = sec (x)

= \frac{d}{d x} (x^{2}) sec (x) + \frac{d}{d x} (sec (x)) x^{2}

\frac{d}{d x} (x^{2}) = 2 x

\frac{d}{d x} (sec (x)) = sec (x) tan (x)

= 2 x sec (x) + sec (x) tan (x) x^{2}
