Question

(a cosΘ,0) and (0,a sinΘ) both dots distance value​

Answer 1

Answer:

Step-by-step explanation:

The distance between (a cosθ,0) and (0,a sinθ) is:

= √(0 - a cosθ)² + (a sinθ-0)²,

= √(-a cosθ)² + (a sinθ)²,

= √a² cos²θ + a² sin²θ,

= √a²(cos²θ+sin²θ),

= √a²(1),

= √a²,

= a units,

________________

cos²θ + sin²θ = 1.
