Transcript text: Approximate the area under the curve $y=x^{3}$ from $x=2$ to $x=5$ using a Right Endpoint approximation with 6 subdivisions.
Solution
Solution Steps
Step 1: Calculate the width of each subdivision
The width of each subdivision, \(\Delta x\), is calculated as \(\Delta x = \frac{b-a}{n} = \frac{5-2}{6} = 0.5\).
Step 2: Determine the x-coordinates of the right endpoints
For each subdivision \(i\), the x-coordinate of the right endpoint, \(x_i\), is calculated as \(x_i = a + i\Delta x\).
Step 3: Evaluate the function at each right endpoint
The function \(f(x)\) is evaluated at each right endpoint \(x_i\) to find \(f(x_i)\).
Step 4: Calculate the area of each rectangle
For each subdivision, the area is approximately \(f(x_i) \cdot \Delta x\), where \(f(x_i)\) is the function value at the right endpoint of the subdivision.
Step 5: Sum the areas of all rectangles
The approximate total area under the curve is \(\sum_{i=1}^{n} f(x_i) \cdot \Delta x = 182.81\).
Final Answer: The approximate area under the curve from \(x = 2\) to \(x = 5\) using a Right Endpoint approximation with \(n = 6\) subdivisions is 182.81.
