Hi,
I have to show that if the derivate f'(x) of a generalized function f(x) is defined by the sequence f'_n(x) where f(x) is defined
f_n(x)[\tex]
then
\int_{-\infty}^{\infty}f'(x)F(x) dx = - \int_{-\infty}^{\infty}f(x)F'(x) dx
I use the limits for generalized functions and...
Hi,
I have to write the 1/(a+ib) as a sum of a real part and an imaginary part.
I was thinking of using the complex conjugate (a-ib) and multiply with this
(a-ib) / (a^2 + b^2)
I am a little bit lost on what to do next - any help appreciated thanks in advance
Best
Thanks
yes I have tried integration by parts but that got very messy.
I don't quite understand how to rewrite the equation involving the anti-derivative?
Best,
Hi,
I have to find a general formula for the function
1/(2n)!\int_{-\inf}^{\inf}x^{2n}*e^{-ax^2}
I am a little bit lost in how to proceed - any hints appreciated thanks in advance
Hi,
I am using the book "Advanced Engineering Mathematics" by Erwin Kreyszig where I am reading on the transformation of coordinates - when changing from \int f(x,y) to \int f(v(x,y),v(x,y) it is necessary to multiply with the size of the jacobian, |J| - I cannot find the proof in the book...
to see if I understand correctly - let's assume that the matrix A har the eigenvalues {1,2,2} and the matrix B has the eigenvalues {-1,1,1} - then it is possible to construct the eigenvectors of B according to the common unique pairs of A and B( (1,1),(2,1),(2,-1)) giving the following...
Hey all,
I have two matrices A,B which commute than I have to show that these eigenvectors provide a unique classification of the eigenvectors of H?
From these pairs of eigenvalue is it possible to obtain the eigenvectors?
I don't quite know how to procede any suggestions?
Thanks...
I don't know if I understand you correctly
M will be 3x2 matrix and EM will 2x2 matrix where with a summation of the each row in M - a(11) summation of first row and a(12) of second row. Rest will be zero
