" 7.If "x=at^(2),y=2at," then "(d^(2)y)/(dx^(2))" is "

If x=at^(2),y=2at then (d^(2)y)/(dx^(2)) is equal to

If x=2at ^(2),y =4at ,then (d^(2)y)/(dx^(2) )=

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

If x=at^2,y=2 at then find (d^2y)/(dx^2) .

If x=at^2,y=2 at then find (d^2y)/(dx^2) .

If x = at^(2) and y = 2 at, then (d^(2)y)/(dx^(2)) at t = (1)/(2) is

If x=2at^2,y=at^4 , then (d^2y)/(dx^2) at t=2 is

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

If x=at^2 , y=at ,then (d^2y)/(dx^2)=
