Hello everyone,
I too had to solve this problem, and I think I found a nice way to write the solution. I'd like to share it here.
We can regroup the harmonic series as follows:
\sum_{n=1}^{\infty} \frac{1}{n} =...
Background:
I am taking an undergraduate fluid mechanics class. I seem to have a misunderstanding with my interpretation of Reynolds Transport theorem (RTT), which I have written below:
$$\frac{DB_{sys}}{Dt} = \frac{\partial}{\partial t}\int_{CV}\rho bd V +\int_{CS}\rho b \vec{V}\cdot...
I reviewed the definition of binding energy. Effectively, binding energy is the energy you need to put in to separate the objects of the system infinitely and at rest. Sense they have to be at rest, I should have calculated the kinetic energy of the moon and added it to the potential energy...
Homework Statement
Consider the earth-moon system (whose constituent pats we take to be the earth and the moon separately).
a) Compute this system's gravitational potential energy (in joules) and the mass deficit (in kilograms). The radius of the moon's orbit is 384,000 km, and its period is...
Hello all,
I am interested in both physics and applied math. One of my professors is willing to work with me to get into a great applied math school, but I don't want to abandon my passion for physics.
Is there work being done at the intersection of applied math and physics?
Is it reasonable...
Hi Ray,
That is a clever idea. I used it to find part of the solution but couldn't get the rest. Not sure what I'm doing wrong.
##3cos(\theta) + 4sin(\theta) = Asin(\theta + \phi)##
##Asin(\theta + \phi) = Asin(\theta)cos(\phi) + Acos(\theta)sin(\phi)##
##Acos(\phi) = 4## and ##Asin(\phi) =...

Thank you all for your insightful replies and questions.
Am I interpreting this correctly... If I start with a vertex and create three vectors from the given points, no matter which three vectors, I will get the volume of the parallelepiped? Even if the vectors are, say, the diagonals of the...
