`(dy)/(dx)` ज्ञात कीजिए-
x = cos t , y = sin t`

Find (dy)/(dx) if x =a ( cos t + t sin t ), y = a ( sin t - t cos t).

x=a cos t, y=b sin t find dy/dx

Find (dy)/(dx) if x =a ( t - sin t), y =a (1- cos t)

Find (dy)/(dx) if x = sin t and y = cos 2t .

Find (dy)/(dx)," if "x=a(cos t+log tan""t/2), y=a sin t .

Find (dy)/(dx) if:- x = - sin t,y= cos t

Find (dy)/(dx) if:- x = sin t,y= cos t

Find (dy)/(dx) : x=a sin 2t (1+ cos 2t) and y= b cos 2t (1-cos 2t) show that, ((dy)/(dx))_(t = (pi)/(4))= (b)/(a)
