Question

Find the distance between the following pair of points: (a sin , - b cos ) and ( - a cos , b sin



Plz write right answer

Answer 1

Answer:

Distance between two points=

(x2−x1)

2

+(y2−y1)

2

⟹

a

2

(sinα−cosα)

2

+b

2

(sinα−cosα)

2

=

a

2

+b

2

(sinα−cosα)

2

=(sinα−cosα)

a

2

+b
