" (t) "(1)/(2x)+(1)/(3y)=2

If x^(2)+y^(2)=t-1/t andx^(4)+y^(4)=t^(2)+(1)/(t^(2)), then prove that (dy)/(dx)=(1)/(x^(3)y).

if x^(2)+y^(2)=t-(1)/(t) and x^(4)+y^(4)=t^(2)+(1)/(t^(2)) then prove that (dy)/(dx)=(1)/(x^(3)y)

If x^(2)+y^(2)=t-(1)/(t) and x^(4)+y^(4)=t^(2)+(1)/(t^(2)) then prove that (dy)/(dx)=(1)/(x^(3)y)

If x^(2)+y^(2)=t-(1)/(t) and x^(4)+y^(4)=t^(2)+(1)/(t^(2)) , show that (dy)/(dx)=(1)/(x^(3)y) .

If x=(1-t^(2))/(1+t^(2)) and y=(2t)/(1+t^(2)), prove that (dy)/(dx)+(x)/(y)=0

If x^2+y^2=t -1/t and x^4+y^4=t^2+1/t^2 then (dy)/ (dx) is equal to a) 1/(x^2y^3) b) 1/(xy^3) c) 1/(x^2y^2) d) 1/(x^3y)

If x=2t+3t^(2),y=t^(2)+2t^(3)," then: "(y_(1))^(2)+2(y_(1))^(3)=

If x^2+y^2=t-1/t and x^4+y^4=t^2+1/(t^2) , then prove that (dy)/(dx)=1/(x^3y)

If x^2+y^2=t-1/t and x^4+y^4=t^2+1/(t^2) , then prove that (dy)/(dx)=1/(x^3y)

If x=a t^2,\ \ y=2\ a t , then (d^2y)/(dx^2)= (a) -1/(t^2) (b) 1/(2\ a t^3) (c) -1/(t^3) (d) -1/(2\ a t^3)
