Thank you!
I spent some time yesterday reading posts and articles about Mathematica, and there was a guy who claimed to had waited for a notebook evaluation about 20 min. :bugeye:
Hello!
I am interested whether it is normal for the program Mathematica to eat 99% from my CPU when evaluating a notebook. Well, it is not just some notebook, but a notebook that contains five matrices, 63 520 entries each.
It would be grate, if somebody has some information on this topic.
Hello!
I have the following problem: I cannot solve the integral below by the means of Matlab.
\int_{-\infty}^{\infty} \frac{e^{-t^2}}{\left(2-t\right)^2 + 16} dt
When I write the following in Matlab
>> syms t;
>> y = exp(-t^2) / (16 + (2 - t)^2);
>> int(y, t, -inf, inf)
it...
Hi!
I have a serious problem solving the following system of differential equations:
m_1\ddot{x_1}=-k_1x_1-k(x_1-x_2)
m_2\ddot{x_2}=-k_2x_2-k(x_2-x_1)
Does anybody have an idea how to solve it?
Thanks.
Yes, I agree. But what about the equations of motion? If , for example, we assume that the electric field is along the y-axis and is perpendicular to the velocity, does it mean that the electric field should be only included in the equation of motion along the y-axis. If so how should the...
Here is the exercise that caused all the trouble:
" Consider a charged particle in a constant electric and a constant magnetic field.
a) Derive the equations of motion.
b) Determine the solution for the velocity.
c) Determine the solution for the position.
d) Make a qualitative drawing...
Thank you for the quick reply!
Thank you for the quick reply, but I still have a problem deriving the formula in CGS.
Does this formula completely describe the motion of a charged particle in constant homogeneous electric and magnetic fields? Did I understand it correctly - the magnetic...
Hi there!
I have a problem deriving the formula for the Lorenz force that I found in my lecture notes in Theoretical Mechanics.
The formula is:
\vec{F}=q \cdot \vec{E} + \frac{q \cdot (\vec{v} \times \vec{B})}{c}
Where:
\vec{F} is the Lorentz force
\vec{E} is the electric...
