If If `y=log_(e)((x^(2))/(e^(2)))`,then `(d^(2)y)/(dx^(2))` equals

If y=log((x^(2))/(e^(2))) then (d^(2)y)/(dx^(2)) equal to: a) -(1)/(x) b) -(1)/(x^(2)) c) (2)/(x^(2)) d) -(2)/(x^(2))

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

If y = (e^(x)+1)/(e^(x)-1), " then" (y^(2))/2 + (dy)/(dx) is equal to

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

If y=a e^(m x)+b e^(-m x), then (d^(2y))/(dx^2) is equals to

If y=sqrt(log{sin((x^2)/3-1)}),t h e nfin d(dy)/(dx)dot

If y=x+e ^(x), then ((d^(2)y)/(dy ^(2)))_(x = ln 2) is :

If y=log_(e)x+sinx+e^(x)" then "(dy)/(dx) is

If y=e^(1+log_(e)x) , then the value of (dy)/(dx) is equal to

If y=500e^(7x)+600e^(-7x) , shows that (d^(2)y)/(dx^(2))=49y .
