1 | Let unc Here we have chosen B as the lower triangular portion of A , and C is of course B — A. We are given that unc To four places of decimals we now find unc and to this order of accuracy , unc is null . |
2 | If A ( which is necessarily square ) is of order n , then clearly the characteristic equation may be written unc The n roots of this equation , say unc are called eigenvalues . |
3 | Let A be partitioned in the form unc Here A is of order n , B of order m , E of order n — m ; C and D are in general rectangular . |
4 | It is difficult to quantify " work " exactly , but if the number of individual multiplications is taken as a guide , then , if A is of order n , each of the n2 elements of unc involves n multiplications : i.e. n3 in all . |
5 | The canonical form of A is thus unc where I is of order r . |
6 | It is easy to find , because it is usually visible with the naked eye at about magnitude 5 , and is in the same binocular field with Beta ; to either side of it are Tau ( 5.1 ) and Sigma ( 4.9 ) , which act as good comparisons , though Tau is of type K and has been suspected of slight variability . |
7 | Diphda is of type K , and is obviously orange ; it has been suspected of variability , but is awkward to estimate , because there are no suitable comparison stars anywhere near it . |
8 | Delta is of type K , and with × 7 or higher magnification is very clearly orange ; it is in the same field as Pi ( 4.4 ) which is a red star of class M. Epsilon ( 3.7 ) is one of the very closest stars , at 10.7 light-years . |
9 | It is of type D , and can be shown to be part of the Taub-NUT solution in the Taub region where there are two space-like Killing vectors . |
10 | The Pole Star is of type F , though I doubt whether anyone will detect yellowness in it ( I certainly can not ) . |
11 | Using × 7 , Rho is in the same field as Sigma ( 4.5 ) which is of type F , but in which I can see no colour at all . |
12 | One star which shows obvious colour is W Boo¨tis , which is of type M and is slightly variable with a range of from 5.0 to 6.4 . |
13 | The main component is of type M , and is one of the largest stars known . |
14 | The only object of any binocular interest is the long-period variable R Horologii , which may reach magnitude 4.7 at maximum although it drops to below 14 at minimum ; the period is 403 days , and the spectrum is of type M , so that the star is very red . |
15 | Alpha is not hard to find , because it is decidedly isolated and forms an equilateral triangle with Regulus and Pollux ; it is of type M , and very red as seen with any binoculars . |
16 | The brighter of the two ( 4.5 ) is of type M , and its obvious redness makes a good contrast with its companion ( 5.5 ) , which is white . |
17 | L2 Puppis is a semi-regular variable with a range of from 3.4 to 6.2 , so that it is almost always visible with the naked eye and is well within binocular range even at minimum ; it is of type M , and clearly orange . |
18 | If the source direction makes an angle θ with the baseline , which is of length d , then the path difference to the two dishes is d cos θ and the phase lag between their signals is at a wavelength λ , and in terms of frequency v this becomes . |
19 | This last is otherwise obvious ; A has only p columns , so that AB , of order ( n × n ) , has at most p linearly independent columns ; i.e. it is of rank p at most , and so must have at least n — p zero eigenvalues . |
20 | We first note that if A is of rank r , then so are |
