Question

The distance between the points Cos, Sin) and (Sin, - Cos) is?​

Answer 1

Step-by-step explanation:

The given points are(cos∅,sin∅) and

(sin∅,-cos∅)

So distance between two given points

=√( cis∅-sin∅)²+(sin∅+cos∅)²

=√ 2(cos²∅+sin²∅). [ (a+b)²+(a-b)²=2(a²+b²)]

=√2×1. [ cos²∅+sin²∅=1]

=√2 unit.
