\frac{d}{d x} (0.7 x^{2})

1.4 x

Solution steps

\frac{d}{d x} (0.7 x^{2})

Take the constant out:

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

= 0.7 \frac{d}{d x} (x^{2})

Apply the Power Rule:

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

= 0.7 \cdot 2 x^{2 - 1}

Simplify

= 1.4 x

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

n = 0 \sum \infty (2 x)^{n}

f (x) = x 2^{x}

(- 2.3) (2.2)

x \to 0 - lim (x \cdot arctan (\frac{1}{x}))
