ST

and

SN

are the lengths of the subtangent and the subnormal at the point

\theta = \frac{\pi }{2}

on the curve

x = a\left( {\theta + \sin \theta } \right),\;y = a\left( {1 - \cos \theta } \right),\;a \ne 1

, then

View answer and explanation

Correct option: A

ST = SN

Option A (

ST = SN

) is correct because at

\theta = \frac{\pi}{2}

, the lengths of the subtangent and subnormal are both equal to

a
