area y=5x^2,y^2= 1/5 x

area

y = 5 x^{2}, y^{2} = \frac{1}{5} x

\frac{1}{75}

Decimal

0.01333 \dots

Solution steps

Isolate

y

for

y^{2} = \frac{1}{5} x : y = \frac{x}{5}, y = - \frac{x}{5}

f_{1} (x) = 5 x^{2}

f_{2} (x) = \frac{x}{5}

To find the intersection points solve

f_{i} (x) = f_{j} (x)

5 x^{2} = \frac{x}{5} : x = 0, x = \frac{1}{5}

5 x^{2} = - \frac{x}{5} : x = 0

\frac{x}{5} = - \frac{x}{5} : x = 0

= \int_{0}^{\frac{1}{5}} ∣ f_{1} (x) - f_{2} (x) ∣ d x

= \int_{0}^{\frac{1}{5}} 5 x^{2} - \frac{x}{5} d x

\int_{0}^{\frac{1}{5}} 5 x^{2} - \frac{x}{5} d x = \frac{1}{75}

= \frac{1}{75}

\frac{d y}{d x} = x^{6} y

x \to 100 lim (8 x)

\frac{1}{4 x ^{\frac{3}{2}}}

\frac{d}{d x} ((x + 3)^{4})

\int_{0}^{2} 4 - x^{2} d x
