Question

find the distance between ( cos A - sin A) ( sin A , cos A)​

Answer 1

Explanation:

Distance between two points (x

1

,y

1

) and (x

2

,y

2

) can be calculated using the formula:

(x

2

−x

1

)

2

+(y

2

−y

1

)

2

Distance between the points (cosθ,sinθ) and (sinθ,−cosθ)

=

(−cosθ−sinθ)

2

+(sinθ−cosθ)

2

=

2(cos

2

θ+sin
