    Nullspace(kernel) and transpose

    hmmm...I have problems understanding this...how can the null space if a matrix(not necessarily a square) be the same as that of its transpose? Thanks in advance

    Is There an Easy Solution for Creating a PC Joystick with Limited Components?

    I was thinking there was any easy way to do this like A transistor which allows current to flow normally and when u put current through its base, it stops? Is that possible?

    Is There an Easy Solution for Creating a PC Joystick with Limited Components?

    power? you mean the +5 v bit and current supply? Yup :P ANd Nope :P you don't want to go to right and left at the same time. Even if some controlloers allowed that, its not possible with that sega controller I have. hmmmm... I have access to some "FET MPF102 N-Ch Junction", I've googled...

    Is There an Easy Solution for Creating a PC Joystick with Limited Components?

    Exactly. The problem is I can only have a NO switch and no NC. And no, you shouldnot be able to press right and left at once.

    Is There an Easy Solution for Creating a PC Joystick with Limited Components?

    hmm.... Well, Ima 1st year student and I've been taught all about resistors and capacitors and inductors. So I decided to use my n00bish skills to change my old saga joystick into a pc one(analog) :P Everything is fine. Learned all about ports and everything I need to make the joypad. Now...

    Polynomials of 2 Variables: General Form & Matrix Representation

    how does one look like?I mean what's the general form? e.g. for a 1 var poly...general form = a0+a1x+a2^2+...+anx^n and how could I represent that by a matrix? Thanks

    Unique linear transformations

    Unique linear transformations! Problems agiain :cry: :cry: :cry: Say I have 2 vector spaces with some finite number of vectors(can assume linear independency)...how can I show that the linear transformation between the two is unique? Thanks in advance!
