Hi-
I have a basic QM problem I am trying to solve. We are just starting on the formalities of Dirac notation and Hermitian operators and were given a proof to do over Spring Break. I am stuck on how to set up the operators and wave equation in matrix and vector form to complete the proof as...
Derivation of "first integral" Euler-Lagrange equation
Homework Statement
This is from Classical Mechanics by John Taylor, Problem 6.20:
Argue that if it happens that f(y,y',x) does not depend on x then:
EQUATION 1
\frac{df}{dx}=\frac{\delta f}{\delta y}y'+\frac{\delta f}{\delta...
This is for a 300 level electronics lab class and I'm wondering if I'm close:

Thanks for the tips. I think I finally got it.
Knowing that \frac{dR}{dt} is constant, R = kt + R0
I also used the mass/volume/density equation suggested above.
I switched variables to get the equation:
\frac{dv}{dR} = \frac{g}{k} - \frac{3v}{R}
(\rho omitted since we are dealing...
This is for a mechanics class. I'm sort of re-learning how to apply calculus and differential equations in this class, so I get stuck trying to figure out how to apply the math I learned 2 or more semesters ago. Any help would be greatly appreciated.
Thanks,
m.g.
