If `x^(2)+y^(2)=1," then "(d^(2)x)/(dy^(2))`

If x^(2) +y^(2) = a then (d^(2)x)/(dy^(2)) = ___________

"If "y= sin x +e^(x)," then "(d^(2)x)/(dy^(2))=

"If "y= sin x +e^(x)," then "(d^(2)x)/(dy^(2))=

"If "y= sin x +e^(x)," then "(d^(2)x)/(dy^(2))=

If y=x+e^(x), find (d^(2)x)/(dy^(2))

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

If e^(y)(x+1)=1, show that (d^(2)y)/(dx^(2))=((dy)/(dx))^(2) If y=sin(2sin^(-1)x), show that ((1-x^(2))d^(2y))/(dx^(2))=x(dy)/(dx)-4y

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