sinh x, cosh x both
First take sinh x d First derivative of sinh x = --- sinh x = cosh x dx d Second derivative sinh x = --- cosh x = sin h x dx
Therefore second derivative of sinh x is sinh x (itself).
Now take cosh x d First derivative of cosh x = --- cosh x = sinh x dx d Second derivative cosh x = --- sinh x = cosh x dx
Therefore second derivative of cosh x is cosh x (itself).
