Step-by-step Solution
To determine the area of the region enclosed by the curves \( y=\sqrt{x} \) and \( y=x^{2} \), we need to find the points of intersection of these two curves and then calculate the area between them.
1. Find the points of intersection:
To find the points of intersection, we need to set the two equations equal to each other and solve for \( x \):
\[ \sqrt{x} = x^{2} \]
2. Solve for \( x \):
\[ x^{2} - \sqrt{x} = 0 \]
\[ x(\sqrt{x} - x) = 0 \]
This equation has two solutions: \( x = 0 \) and \( x = 1 \).
3. Calculate the area between the curves:
The area between the curves can be calculated by integrating the difference between the two functions over the interval where they intersect. The interval of interest is from \( x = 0 \) to \( x = 1 \).
The area \( A \) can be calculated as:
\[ A = \int_{0}^{1} (\sqrt{x} - x^{2}) dx \]
Let's calculate the integral to find the area.
Evaluate the integral by following steps:
- step0: Evaluate using formulas and rules:
\(\int_{0}^{1} \sqrt{x}-x^{2} dx\)
- step1: Evaluate the power:
\(\int_{0}^{1} x^{\frac{1}{2}}-x^{2} dx\)
- step2: Evaluate the integral:
\(\int x^{\frac{1}{2}}-x^{2} dx\)
- step3: Use properties of integrals:
\(\int x^{\frac{1}{2}} dx-\int x^{2} dx\)
- step4: Evaluate the integral:
\(\frac{2}{3}x^{\frac{3}{2}}-\frac{1}{3}x^{3}\)
- step5: Return the limits:
\(\left(\frac{2}{3}x^{\frac{3}{2}}-\frac{1}{3}x^{3}\right)\bigg |_{0}^{1}\)
- step6: Calculate the value:
\(\frac{1}{3}\)
The area of the region enclosed by the curves \( y=\sqrt{x} \) and \( y=x^{2} \) is \( \frac{1}{3} \) or approximately 0.333.
Quick Answer
The area enclosed by the curves \( y=\sqrt{x} \) and \( y=x^{2} \) is \( \frac{1}{3} \) or approximately 0.333.
