    Exploring the Limit of $\frac{1}{x} \int_0^x (1-tan2t)^{\frac{1}{t}}dt$

    just take the integral first then it will be real easy to do this question

    Prove that the lim (x->1) x^2 + 2 is NOT equal to 2.999?

    my friend it's real simple; as the 2 won't be effected by the limit, so only part affected by limit is x^2 when x->1 although u are write it might go to 2.999 when it approach from left, but u need to consider another fact when limit approach from right than it will be 3.00001 that's...

    I have trouble understanding the concept of resonance

    resonance is just shifting of your electrons from one carbon to another or u can say shifting of bonds

    Momentum in Inelastic Collisions

    i tink u mis understood the conservation of linear momentum. it says whenever u one object having mass m and velocity v collide with another then the momentum of that body will be the same mv. if its heavier then it will have less velocity and if its lighter then it will have more velocity.

    Your Thoughts: speed of gravity

    i think gravity is a force just like an electric field which have it's own area or a region where it's effective and it is constant it neither have speed nor acceleration.But it has a power to attract things with the same pull which we say 9.8 m/s^2. what u guys think of my post

    The Debate on Light: Particle or Wave?

    light has both the nature of wave and particle, as according to de broglie he showed his work as folllowing Einstein said e=mc^2 so this is particle nature and max Planck said h=wc where w is wavelenght and c speed of light => c=h/w and e=mc^2 =>...
