Detailed Problem Solution
This final page provides a comprehensive solution to the whirlpool design problem introduced earlier, demonstrating the application of various calculus techniques.
The solution process includes:
- Calculating intersection points of the boundary functions
- Setting up and solving the integral to find the area between the functions
- Computing the volume of water in the pool
- Determining the angle at which the curves meet
Example: The water volume is calculated by multiplying the area 19.2m2 by the pool depth 1.5m, resulting in 28,800 liters of water.
The page also covers the calculation of the Anstiegswinkel angleofinclination between the curves at their intersection point:
- Finding derivatives of both functions
- Evaluating derivatives at the intersection point
- Calculating the difference in slopes
- Using inverse tangent to determine the angle
Vocabulary: Anstiegswinkel - The angle of inclination or slope angle between two curves at their intersection point.
Highlight: The final step uses the arctangent function to convert the slope difference into an angle, resulting in -45°.
This comprehensive solution demonstrates the practical application of integral calculus and differential calculus in solving complex, real-world problems.
