Then what do we use to find the value of the turning point? What if u can't use dy/dx = 0 for it? I mean what if u don't get an answer for it...u add and subtract .1 or something na? Could u explain that to me

No. Fifth means 4-5, so you'll take the range 5 and 4.

No, for a given equation, you calculate dy/dx, let dy/dx = 0, calculate x, put the value of x in the equation to find y and get your coordinates for the turning point.

Yeah I know that. Ok ok you add/ subtract o.1 to find the nature of the turning point when u can't find the value of x for d2y/dx2.. Sorry I got confused

Haha so do I
and yes that could happen..like if u can't differentiate further or if your x value turns out to be zero or something. In that case add and subtract .1... @saadmughal what do we subtract it from?

He was saying in general BANGLADESHI's not talking about Sourov. Plus, if he says he doesn't like to cheat then why question him?

Hey that total of fence I calculated came to be 832 and further upin decimal to two places but I guess answer was more than 1000 as we had to find 220 percent while I guess I found 120 percent using ratio method as I wrote 100 percent in 378 so how much will be in 220 but will my all marks be gone,I am worried and that was in locus question we had to use Pythagoras theorem,I used it,some measured it,and I forgot to write answer to AF but wrote 7 cm in working I guess
