Hi,
Assume that we have a function x(t) where t is time.
I want to linearize a function to use Laplace Transform
So, assume that we have following terms
\[\beta\](x(t))*x(t) + \[\beta\](x(t-h))*x(t-h)
where
\[\beta\](x) = 1/(1 + \[{x}^{5}\])
Here how can I linearize it to by using Taylor...
I think, it is similar to ElectroStatics case. F = m*g and F = E*q where m-q and g-E are dual. Ergo, I think in the first equation, g is a vector since m is scaler and F is a vector. So we can say gravity is a vector and it is proportional to gravitational force with mass factor.
Hi,
If we have a conducting disk (with constant electric potential = V where V > 0) and we divide disk as shown in attached file, where distance between two subdisk is equal, is it possible to have total negative charge over some subdisk in static case?
Thanks;
Hi, I am trying to write a Matlab code that works for charged conducting Plate. Spesifically, the problem is from R.F. Harringston's "Field Computation by Moment Method" Ch2.2
I have following codes, but that does not work for the cases if I choose number of subsections more than one.
Here are...
Hi,
In my Electromagnetics Theory book, wave equations have attached solution, where Spherical coordinate system is used and R is distance, Up is the velocity of wave propagation, pv is charge density of the volume.:
Can someone tell me how to use (t-R/up) term in this equation? I mean V is...
Re: PI number in fortran
I am new in Fortran. I have seen an exercise in a book (Fortran 95 2003 for Scientists and Engineers) and the problem states, we want to calculate tangent of an angle, but since the tangent is simply sin(x) / cos(x), if we have cos(x) < 10^(-20) give an error message...
Hi, how can I create PI number in fortran?
I used REAL, PARAMETER :: PI = 3.14159265358979323846264338327950288419716939937510
statement and also this number that is obtained by Gregory–Leibniz series:
PI = 16*ATAN(1./5.) - 4*ATAN(1./239.)
I applied them into WRITE(*,*) TAN(PI*THETA/180)...
Hi fellows,
I am a sophomore-end student and I have agreed with one of my professor to research with him. I have no prior knowledge about Electromagnetism, Just Freshman Physics course. I took Calculus, Linear Algebra and DE Classes. This summer, I will study on D.K. Cheng's electromagnetics...
I am a sophomore student in Electronicss Engineering. I want to do academic research about this antenna engineering with one of my professor. I took calculus classes. We started differential equations. By now, for EM, Could you share some websites, or books, or textbooks?
Re: problem with GCLK
After 5 years, I faced this problem and I couldn't find any solution on the net. However, I solved this warning:pack:266 problem.
I wrote codes for my course project, specifically for frequency counter implemented on basys2. I wrote a VGA module and it gives yellow color...
