A curve is represented by the equations, \( x=\sec ^{2} t \) and \( y= \) \( \cot t \) where \( t \) is a parameter. If the tangent at the point \( P \) on the curve where \( t=\pi / 4 \) meets the curve again at the point \( Q \) then \( |\mathrm{PQ}| \) is equal to :https://bit.ly/YTAI_PWAP https://www.pw.live
