Question

find the distance between,(asinα,-bcosα) and (-acosα,bsinα)?

Answer 1

$\huge\boxed{\fcolorbox{red}{yellow}{Shailesh}}$

Distance between the points is

a(\sqrt{(cos \alpha -cos \beta )^{2}+(sin \alpha -sin \beta )^{2}} )

a(\sqrt{(cos^{2} \alpha +sin^{2} \alpha )+(cos^{2} \beta +sin^{2} \beta )-2cos \alpha cos \beta -2sin \alpha sin \beta })

a(\sqrt{2(1-cos( \alpha - \beta) ) } )

Hence distance between them is 2|a(sin(\frac{ \alpha - \beta }{2}))|.
