यदि `x=a sin 2t (1+cos 2t ) ` व ` y=bcos 2t (1-cos 2t ) ` तब दिखाइए की ` ((dy)/(dx) )_(x=(pi)/(4) ) =(b)/(a) `

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)

x=a sin 2t(1+cccos 2t ),y=b cos2 t (1-cos 2t) find dy/dx

If x = a sin2t(1+cos2t) and y =b cos 2t(1-cos2t) , then show that ((dy)/(dx))_(t=pi//4) = (b)/(a) .

If x = a sin2t(1+cos2t) and y =b cos 2t(1-cos2t) , then show that ((dy)/(dx))_(t=pi//4) = (b)/(a) .

If x=a sin2t(1+cos2t) and y=b cos2t(1-cos2t), find the values of (dy)/(dx) at t=(pi)/(4) and t=(pi)/(3)

x= a sin 2t(1 + cos2t) and y = b cos 2t(1- cos 2t) , show that [(dy/dx)_(t=pi/4) =b/a] .
