Inversion Definition and 108 Threads

I need to express the sinh-1(x) as a power series in terms of powers of x. I have written the expression as x=sinhy and expanded the sinhy using the exponential series to give x = y+(1/3)y^3+(1/5)y^5+... I guess I need to expand the y=sinh-1(x) and compare or equate the coefficients. If this...

i can perfom the same inversion in two ways: 1. using N data and k model parameters 2. using 3*N data and k+3 model parameters where N>>k. how can I choose the best result between the two? thanks

Can someone with a graphing calculator give me the inverse of this matrix? \begin{array}{ccc} 0&1&2\\ 1&0&3\\ 4&-3&8 \end{array}

hi, does anyone know the character table for the inversion group?

i have got a TAT but when it becomes TAC, this is called an insertion, I think its the same as deletion, or inversion, so I am stuck at how to make a difference between them ? Can you help me ?thanx

insertion, deletion, inversion ? Help me with examples please, thanks

OK, I realize this may be more geophysics then "geology", but I beg for leniency. I have recently been exchanging e-mails with Dr. Daniel Lathrop of the University of Maryland. He is currently involved in a project attempting to model the Earth's magnetic field and, in particular, polar...

Anybody know of a link to a page that describes an algorithm for matrix inversion. My old linear algebra book describes a 'by hand' method, but it's unsuitable for automating.
