WebAnswer (1 of 2): Answer is x = a cos ϴ , y = a sin ϴ [Because by squaring and adding these we will get x² + y² = a² cos²ϴ + a² sin²ϴ x² + y² = a²( cos²ϴ + sin²ϴ) x² + y² = a² using cos²ϴ + sin²ϴ=1 x² + y² = a²] WebJun 14, 2024 · We know that cos t is the x -coordinate of the corresponding point on the unit circle and sin t is the y -coordinate of the corresponding point on the unit circle. So: x = cos t = 1 2 y = sin t = √3 2. Try It 2.2.1. A certain angle t corresponds to a point on the unit circle at ( − √2 2, √2 2) as shown in Figure 2.2.5.
