I think next one will have only 2 vowels in his name.

I will solve the second one for you
y = Root(Cosecx)
y Square = Cosecx
I will use & for delta
(y +&y)square= Cosec(x+&x)
y Square + 2y&y = Cosec(x+&x) {Neglecting &ySquare to be small)
2y&y = Cosec(x+&x) - Cosecx
2y(dy/dx) = -cosecxcotx

dy/dx = -cosecxcotx / 2 Root(cosecx)

I am student of class 12. I am not studying for boards right now.

My plan is only IIT

But i Have a problem intially i was nice in Maths but slowly my performance is declining i am extremely worried.

I am not solving problems in the fear that they could further low my confidence level.

I am lost please guide me to my goal

Always remember
To remember you must revise.
So after completion of your course atleast a month long revision is very very important.
without it IIT is impossible.

Hi Aakriti,
To give a good suggestion i would like to know your aim is it IIT or AIEEE or anything else.

A particle is thrown straight up into the air at 25 metres per second. what the distance is travelled by it in the third second.(Take g =10 for convenience)
