Re: Matlab problem
Hi,
I think that the error you get is due to that you didn't install the symbolic math toolbox or the extended math toolbox. This i ssolved nby installing them from the MatLab source.
Hope this helps,
If your 8 by 8 matrix has rank =8 then all its columns are the basis but if the rank is less, some columns are dependent and do not form a basis. For example if u put a column and then u multiply by 2,3 4,... all columns are dependent and u get one basis vector.
Best wishes,
Dear electronics_kumar,
When u get Laplace Transform of a fn as a function in s , You can substitute
s=sigma + j*omega.
and then plot this as a function of both sigma and omega which is shown as the surface on the RHS. If you put sigma =0 (cutting the surface by a plane) I get Fourier Transform...
Re: challenge question ..
Hi Basil,
What I meant by no sources is what u agreed with which is fields can exist by themselves with no need of 'continious' sources like the example of an oscillating electron but of course a source must have generated fields otherwise we would get energy from...
Hi everyone,
Just a quick note :
The formula you put(cos(x)/(sqrt(1-sin^2(x)) can be simplified easily into 1
That's because y=arcsin(sin(x))=x
and hence y' =1

integral sin catalan
Hi,
This is not correct because cos(cos(90-x) is not equal to cos^(90-x) whis is equal to cos(90-x)*cos(90-x).
It can only be integrated numerically unless it has limits of 0 to pi where it's Bessel function..

Re: challenge question ..
Hello everyone,
I just have some points to say:
*First an electron can radiate energy in the form of photons or electromagnetic waves if u want but also it can absorb photons as we know for an electron inside the atoms, and through all its life it keep like this...
integration sin(sin(x))
Hi,
If this integral has limits of 0 to pi it will be equal to pi*J(0,x) where J(0,x) is Bessel function of order zero.

Hello,
I am not sure but I think that we can imagine things which do not exist physically and talk about them.
It's like when we talk about asin(3) we know that sin is between -1 and 1 but in complex plane we can get inverse sines greater than 1.
Also I remember reading an essay on negative...
Hi,
Well we can say that probability if the main difference between classical and quantum physics, other differences are based on the uncertainty based on the fact that everything is probablilistic (as we mentioned interference of probability waves which is called dual aspect...)
But there is...
