Linear Algebra I exam
In four hours I will be writing the second part of my linear algebra exams. I "only" need to get 23 of 50 points. Wish me luck!

Linear Algebra isn't too bad, I just hope they don't make you invert a 4 by 4 matrix by HAND.
It does come in handy for things like numerically solving Laplace's Equations over all space for an irregularly mapped coordinate system. |

This might frighten you, but I actually know how to take the square root and cube root of <em>any</em> given number (including decimals) by hand on a sheet of paper. Its kinda like long division, and helps in a pinch when you forget your calculator on an exam... |

i can find the nth root of any number of arbitrary precision. the general algorithm is called Newton's Method in North American calculus textbooks and finding roots of real numbers is only one of its applications: x_(i+1) = x_(i) - f(x_(i))/f'(x_(i)) (where x_(i)'s are approximations of the root of f) and let f(x) = x^n - a then f'(x) = (n)x^(n-1) to find the nth root of a. [edit] check this out: http://mathworld.wolfram.com/NewtonsMethod.html ("A fractal is obtained by applying Newton's Method to finding a root of z^n - 1 = 0" ie.: nth complex root of 1) [/edit] Last edited by agent; 15th Feb 2002 at 01:54 PM. |

Well, it's all over now. Going by my gut feeling I should have enough points.
@electric sheep: one of the things we had to do was inverting a 3*3 matrix... I half forgot how to do it. Grrr. The rest was relatively ok. Eigenvalues, characteristic polynom, minimal polynom, determinants,... Either way it's time to get drunk after I'm finished typing this
