Create professional Manim animation code that explains mathematical concepts clearly and elegantly. Your code MUST:



TECHNICAL REQUIREMENTS:

1. Use 'from manim import *' at the top

2. Create a Scene class named 'ManimScene' that extends Scene

3. Implement the construct method correctly

4. Use only standard Manim Community edition objects and methods

5. Include proper self.play() and self.wait() calls with appropriate durations

6. Use valid LaTeX syntax for all mathematical expressions

7. Be fully compilable without errors

8. Include helpful comments explaining each section

9. Just return python code, do not include apostrophe in front and back of code



VISUAL STRUCTURE AND LAYOUT:

1. Structure the animation as a narrative with clear sections (introduction, explanation, conclusion)

2. Create title screens with engaging typography and animations

3. Position ALL elements with EXPLICIT coordinates using shift() or move_to() methods

4. Ensure AT LEAST 1.5 units of space between separate visual elements

5. For equations, use MathTex with proper scaling (scale(0.8) for complex equations)

6. Group related objects using VGroup and arrange them with arrange() method

7. When showing multiple equations, use arrange_in_grid() or arrange() with DOWN/RIGHT

8. For graphs, set explicit x_range and y_range with generous padding around functions

9. Scale ALL text elements appropriately (Title: 1.2, Headers: 1.0, Body: 0.8)

10. Use colors consistently and meaningfully (BLUE for emphasis, RED for important points)

11. Preventing overlaps of element, choose position for each element carefully, display element and text then move to next element



ANIMATION TECHNIQUES:

1. Use FadeIn for introductions of new elements

2. Apply TransformMatchingTex when evolving equations

3. Use Create for drawing geometric objects

4. Implement smooth transitions between different concepts with ReplacementTransform

5. Highlight important parts with Indicate or Circumscribe

6. Add pauses (self.wait()) after important points for comprehension

7. For complex animations, break them into smaller steps with appropriate timing

8. Use MoveAlongPath for demonstrating motion or change over time

9. Create emphasis with scale_about_point or succession of animations

10. Use camera movements sparingly and smoothly



EDUCATIONAL CLARITY:

1. Begin with simple concepts and build to more complex ones

2. Reveal information progressively, not all at once

3. Use visual metaphors to represent abstract concepts

4. Include clear labels for all important elements

5. When showing equations, animate their components step by step

6. Provide visual explanations alongside mathematical notation

7. Use consistent notation throughout the animation

8. Show practical applications or examples of the concept

9. Summarize key points at the end of the animation
