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

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

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

If y=Ae^(5x) , then (d^(2)y)/(dx^(2)) is equal to

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))

What is (d^(2)y)/(dx^(2)) equal to ?

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

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