Optimization
Optimization comes from the same root as "optimal". "Optimal" means the highest. When you do the optimization process, that is when you are "making it best" to maximize everything and to achieve optimal results, a set of parameters is the base for the selection of the best element for a given system.
Integration
Integration means to sum the things. In mathematics, it is the branch of Calculus which is used to find the area under the curve. The operation subtraction is the inverse of addition, division is the inverse of multiplication. In the same way, integration and differentiation are inverse operators. Differential equations give a relation between a function and its derivative.
Application of Integration
In mathematics, the process of integration is used to compute complex area related problems. With the application of integration, solving area related problems, whether they are a curve, or a curve between lines, can be done easily.
Volume
In mathematics, we describe the term volume as a quantity that can express the total space that an object occupies at any point in time. Usually, volumes can only be calculated for 3-dimensional objects. By 3-dimensional or 3D objects, we mean objects that have length, breadth, and height (or depth).
Area
Area refers to the amount of space a figure encloses and the number of square units that cover a shape. It is two-dimensional and is measured in square units.
![## Calculating Volume Using Cylindrical Shells
To find the volume of a solid obtained by rotating the specified region around the y-axis, we will use the method of cylindrical shells.
### Problem Statement
Use cylindrical shells to find the volume of the solid obtained by rotating the region bounded by the curves \( y = x^2 \), \( y = 0 \), and \( x = 1 \) about the y-axis.
### Setup
Given the boundaries:
- \( y = x^2 \) (a parabola)
- \( y = 0 \) (the x-axis)
- \( x = 1 \) (a vertical line)
### Solution Steps
1. **Determine the height and radius of a typical shell:**
- Height (h) of the shell at any point \( x \) is given by the function: \( h = y = x^2 \).
- Radius (r) of the shell: Since we are rotating around the y-axis, the radius is equal to the x-coordinate \( x \).
2. **Express the volume element:**
- The volume element (dV) of a cylindrical shell is: \( dV = 2\pi x \cdot (x^2) \cdot dx = 2\pi x^3 \, dx \).
3. **Integrate to find the total volume:**
- The limits of integration are from \( x = 0 \) to \( x = 1 \).
- The volume \( V = \int_{0}^{1} 2\pi x^3 \, dx \).
4. **Calculate the integral:**
- \( V = 2\pi \int_{0}^{1} x^3 \, dx \).
- \( V = 2\pi \left[ \frac{x^4}{4} \right]_{0}^{1} \).
- \( V = 2\pi \left( \frac{1}{4} - 0 \right) \).
- \( V = \frac{\pi}{2} \).
### Final Answer
\[ V = \frac{\pi}{2} \]](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F77ae9024-98f9-40e2-9992-1c0ab1fe204c%2F770398fc-377b-4419-b420-66e8d74eba82%2Fp85eh8_processed.png&w=3840&q=75)
