thanks; lol i didnt saw it

m\frac{dv}{dt}= mg - kv^{2} constants: m, g, k. I tryed and i can't find a solution to this diferential equation.

Dont let the age bother you!

Thanks people; i did a mistake of signs lol.

Integral of ((Tan x)^6)dx i think that the solution is: (1/5)(tan x)^5 + (1/3)(tan x)^3 - (2/3)(tan x)^3 + tan x - x + c but if i derivate this solution it lead me to that: (tan x)^4((tan x)^2 + 2) ?:confused:

lol, it is normal to a physicist to get drunk (I mean not too drunk) once a week? Neumann had a great social life.

Im afraid of that. So how much do you think i had to pay in average?

Please can you explain me.

How much money do you have to spend doing a Phd (physics)?

Can a computer science degree help a physicist? :confused:

Im just wondering that who has a PhD in this forum?

I speak chinese, english and spanish.

Merry Christmas! The beginning of a great year for studies..

What plans do you have for the holiday?
