I need a thorough explanation Rankeya has given a valid answer to the written question, but i realize now i was too vague Secondly, i looked up the correct exercise in jacobson and found that the following exercise is precisely to show that it does hold for all division rings Stupid gut feelings.i'm accepting this answer and reposting the correct question. To gain full voting privileges, Eigenvectors corresponding to distinct eigenvalues of a symmetric matrix must be orthogonal to each other
Eigenvectors corresponding to the same eigenvalue need not be orthogonal to each other However, since every subspace has an orthonormal basis, you can find orthonormal bases for each eigenspace, so you can find an orthonormal basis of eigenvectors. As noted in the comments, your derivation contains a mistake To answer the question, this function can not be integrated in terms of elementary functions So there is no simple answer to your question, unless you are willing to consider a series approximation, obtained by expanding the exponential as a series $$\int {x^xdx} = \int {e^ {\ln x^x}dx} = \int {\sum_ {k=0}^ {\infty}\frac {x^k\ln.
Upvoting indicates when questions and answers are useful What's reputation and how do i get it Instead, you can save this post to reference later. I understand the meaning of $\frac {dy} {dx}$ and $\int f (x)dx$, but outside of that what do $dy, du, dx$ etc. When i took calc i, derivatives and integrals. According to symbolic matlab and wolframalpha, $\\frac{\\partial x(t)}{\\partial x} = 0, \\frac{\\partial x}{\\partial x} = 1$ i came across this while trying to.
