adnrewkirk, if the integral of 1/cosx blows up that means it is not correct answer. I actually thought that it is directly proportional to 1/v or 1/(v^2) but it is not the case, the integral does not make sense or it blows up using this logic.
Homework Statement
We know that after long run of simple mass-spring system, there should be a probability of finding the mass at certain points between -A and A.. Obviously in probability of finding the particle near A or -A is higher than finding the particle at 0, because the speed is the...
In calculus of variations when we solve Euler's equation we always do think of y, x and y' as independent variables.
In thermodynamics we think that different potentials have totally different variables
I don't understand why the slope of the function is not directly dependent on function itself.
Homework Statement
Proove it
Iam supposed to change coordinate system, and proove that the result depends on coordinate system.
The Attempt at a Solution
My attempt was to start from definition of cross product using levicivita. I already prooved that divergence of a vector is a scalar. But...
It is too tedious to do so, and if you are going too fast they become like an mess on the top of a bar. Arrows are definitely not the best choice for me.
