derivative of

y = 7 x^{3}

21 x^{2}

Solution steps

\frac{d}{d x} (7 x^{3})

Take the constant out:

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

= 7 \frac{d}{d x} (x^{3})

Apply the Power Rule:

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

= 7 \cdot 3 x^{3 - 1}

Simplify

= 21 x^{2}

\int \frac{x ^{2}}{1 - x ^{6}} d x

\int x cos (x) d x

x \to - 7 lim (\frac{6 x + 42}{x + 7})

t an g e n t f (x) = 3 x^{3} + 4 x^{2}, (- 1, 1)

\frac{d}{d x} (7^{2 x})
