Hi! First,i divide both side of the equation by 2kl,then define a to be equal to mg/2kl,so the equation would be as follows, acos(x)+sin(x)-{cos(x).sin(x)}=0,in which i replaxe the fi notation by "x". Now by taking {cos(x).sin(x)}to the right then squaring both sides we have, (a^2)((cos(x))^2)...

Hi Ankit! The truth is,for olympiad one should solve many problems.You could find the lessons in every books.I recommend you get all of them,and solve the problems available on them.I also think the Morin's mechanics got the soloutions on itself too. David cheng's electromagnetic and Nayfe's one...

Non sence!

Thanks!"that energy function you're talking about is between f(Tmax)*V "The continuity gives us that f(Tmin)<f(T)<f(Tmax) so f(Tmin)V<f(T)V<f(Tmax)V,but how did you derive the statement above on internal energy?!

I can't understand some aspect of using calculus in physics.Here,i explain what i mean as an instance.Please give me your points on it. Let T to be temperature of a cubic solid,and any point of the solid could have different temperature.Suppose by experiment and other ways we know that if T be...

Thanks a lot,

Thanks a lot,
