\frac{d}{d x} (x 64 - x^{2})

\frac{- 2 x ^{2} + 64}{64 - x ^{2}}

Solution steps

\frac{d}{d x} (x 64 - x^{2})

Apply the Product Rule:

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

f = x, g = 64 - x^{2}

= \frac{d x}{d x} 64 - x^{2} + \frac{d}{d x} (64 - x^{2}) x

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

\frac{d}{d x} (64 - x^{2}) = - \frac{x}{64 - x ^{2}}

= 1 \cdot 64 - x^{2} + (- \frac{x}{64 - x ^{2}}) x

Simplify

1 \cdot 64 - x^{2} + (- \frac{x}{64 - x ^{2}}) x : \frac{- 2 x ^{2} + 64}{64 - x ^{2}}

= \frac{- 2 x ^{2} + 64}{64 - x ^{2}}

\int_{0}^{5} π (25 - x^{2}) d x

x \to 4 lim ((x + 3)^{2})

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