Wah, maths question? Arre, I wouldn't know about 'stationary point' la, but I know about stopping point – that's when my old Bullet stops for good! If you want to prove something's at its maximum, in my life, you just know. Like when the rain is heaviest on the Kohima road, you feel it. You can't go further, so you wait for it to slow down. Maybe check your book again, brother.
