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

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

Solution steps

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

Treat

d

as a constant

Take the constant out:

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

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

Apply the Product Rule:

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

f = tan (x), g = x

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

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

\frac{d x}{d x} = 1

= d (sec^{2} (x) x + 1 \cdot tan (x))

Simplify

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