No it wasn't easy. But I found it easier than other topics eg. Transformations
Especially as I am doing physics we've done motion and I had already been thinking
that there must be an easier more systematic approach, then along came i and j.
Is there anything specific you need help with? Just post a question up, I know this board is fairly dead but everyone will still help. :)

Yeah I reckon its easier than some other parts of the course as well. I think its ok once you get a good grasp of the fact that they rely heavily on direction and not just length. Have you guys done dot multiplication of vectors? What about resolutes and time-varying vectors. Our teacher just added them in from the 3/4 textbook and I was wondering if anyone else has done them. They are slightly harder than regular vectors and while revising from the 1/2 book they made vectors seem so much easier. But at the start they were a struggle

Yeah I think that I like them compared with some other maths. But I'll have to wait and see how I feel about them after the test. :)

Yeah it seemed to be alright, but i guess i wont really know until i get it back.

Wow i found the 3d stuff like the easiest part of vectors..

m@tty, i use the same textbook as you! haha except teacher gave us extra sheets on scalar product and stuff.
