  3. Sugar Cookies/Sin • Sugar (2Ɵ) = double batch of sugar Recipe = 2SugarCookies • Sine(2Ɵ) = 2sin(Ɵ)Cos(Ɵ)

  4. Chocolate • Chocolate(2Ɵ) = double batch of chocolate = Cosine(2Ɵ) Recipe= ChocolateChip- SweetSugar Cos(Ɵ)Cos(Ɵ) – Sin(Ɵ)Sin(Ɵ)

  5. Cosine Ɵr 2ChocolateChip - 1 2Cos(Ɵ)Cos(Ɵ) – 1 Ɵr 1 – 2SweetSugar 1 – 2Sin(Ɵ)Sin(Ɵ)

  6. Thin Mint • Thin Mint(2Ɵ)= double batch of thin mint • Recipe= 2Teaspoons/ (1-TeaspoonTablespoon) Tangent • Tan(2Ɵ) = • 2Tan/ (1 - Tan(Ɵ)Tan(Ɵ))
