Riemann Sum
Riemann Sums is a special type of approximation of the area under a curve by dividing it into multiple simple shapes like rectangles or trapezoids and is used in integrals when finite sums are involved. Figuring out the area of a curve is complex hence this method makes it simple. Usually, we take the help of different integration methods for this purpose. This is one of the major parts of integral calculus.
Riemann Integral
Bernhard Riemann's integral was the first systematic description of the integral of a function on an interval in the branch of mathematics known as real analysis.
Question
![The image presents a contour map for a function \( f \) over the square \([0, 4] \times [0, 4]\). It includes contour lines at different levels, marked with values ranging from 1 to 9. The contours are represented as curves drawn across a grid defined by the x-axis (horizontal) and y-axis (vertical). Both axes range from 0 to 4.
### Explanation of the Contour Map:
- **Grid Overview**: The grid is a square divided into smaller squares with dimensions defined by integer coordinates, spanning from 0 to 4 on both axes.
- **Contour Lines**: These lines represent levels of the function \( f(x, y) \) at specific values, helping visualize the function as a 3D surface on a 2D plane.
- Contour levels shown are 1, 2, 3, 4, 5, 6, 7, 8, and 9. Each contour line connects points where the function \( f \) reaches these respective values.
- Lines are closer together where the function changes more rapidly.
### Question and Tasks:
1. **Midpoint Rule Estimation**:
- Use the midpoint rule with \( m = n = 2 \) to estimate the integral \(\iint_R f(x, y) \, dA\), where \( R \) refers to the domain \([0, 4] \times [0, 4]\). The result should be rounded to the nearest integer.
2. **Average Value Estimation**:
- Estimate the average value of the function \( f \), rounded to the nearest tenth.
These tasks involve mathematical estimation techniques useful in calculus, particularly in approximating integrals and interpreting contour maps.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F75449ef3-fcc1-42e7-9af4-d9c30b92c4e1%2F6be84810-4d40-439e-a66e-ff67ad735e21%2F4z2nb8e_processed.png&w=3840&q=75)
