Answer 2

integrate it and then keep it eqyal to zero

Answer 3

take derivative!!!

Answer 4

sorry i mean diffrentaite it and keep it equal to zero

Answer 5

no we differentiate and then put f''(x)=0, but how to do this in mathematica?

Answer 6

u know u/v formula

Answer 7

because mathematica doesn't solve f''((Sin[x])/x)==0

Answer 8

listen bro when u integrate it the sinx/x factor changes
