Taylor Series Approximation

Description

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
