MY DEAR I MADE A TYPO IN d2y/dx2
SOORY 4 THAT
BUT I DIDNT USED IT MUCH[1]
AUR BHAI
==> cosx = 0 or sinx=1 .. u hav made a mistake there..
THIS IS CORRECT
BECAUSE IF U PUT x=pi/2 or x=pi/6
equality holds 4 both[1][1][1]

BHAI
LOGIC : WE CAN CANCEL ANY EQUATION IF IT DOES NOT BECOME 0=0 FORM OR ∞=∞FORM
I HAD ALREADY TAKEN CARE OF 0=0 i.e pi/2[1]
