Taylor Series Approximation
简介
Demonstrates how the Taylor series builds increasingly accurate polynomial approximations of cos(x) around x=0 by successively adding terms. Each new term is animated in a new color, revealing how the approximation extends further from the center.

Phases
| # | Phase Name | Duration | Description |
|---|---|---|---|
| 1 | Setup | 5s | Title, axes, plot cos(x) in white |
| 2 | T₀ = 1 | 6s | Plot constant term, explain 0th-order approximation |
| 3 | T₂ = 1 - x²/2 | 7s | Add quadratic term, new color, better fit near origin |
| 4 | T₄ = 1 - x²/2 + x⁴/24 | 7s | Add quartic term, fits further out |
| 5 | T₆ = add -x⁶/720 | 7s | Add sixth-degree term, excellent fit over wider range |
| 6 | T₈ | 6s | Add 8th-degree term, near-perfect over [-π, π] |
| 7 | Formula display | 8s | Show general Taylor series formula, error term O(x^n) |
| 8 | Summary | 4s | All approximations overlaid, convergence message |

Assets & Dependencies
- Fonts: LaTeX
- Manim version: ManimCE 0.19.1
Notes
- cos(x) Taylor series centered at 0: Σ (-1)^n x^(2n)/(2n)!
- Terms: 1, -x²/2!, x⁴/4!, -x⁶/6!, x⁸/8!
- Colors cycle: RED → ORANGE → YELLOW → GREEN → TEAL
- Use axes x_range = [-2π, 2π], y_range = [-1.5, 1.5]
- Clip polynomial plots to avoid large values far from origin
