Maths recommendation.
-
I am about to start University for a Computer Science degree however my maths skills are not great (GCSE level 2) as I haven't done A levels maths... Maths has always been a struggle for me as the tutors seemed more concerned on the "higher" students than "middle grade"... Can anyone recommend a on-line resource or book for learning some maths higher than GCSE level 2 as allot of algorithm books (especially game development books) contain lots of wonderful symbols and structure which I do not know (or know how to search for them as I do not know the names)? :-D
Well, Mathematics is a broad and beautiful subject. You'd have to be a bit more specific with your question to get a really good answer regarding a resource. I can suggest two things however. The first is that Maths, like anything, needs a lot of hard work, so much more so than intelligence, to be good at it. Intelligence makes the route shorter, but hard work gets you there all the same. So have at it with a brave heart :) The second, and I use this from time to time mostly for things other than Maths, is the OCW from MIT (Clickety[^]). This has several, some more advanced than you'd care or want, fantastic classes with quite a few having video lectures. After seeing some of those lectures, you can really understand why MIT is such a fine institution, the lecturers are excellent. There is one or more on Mathematics for Computer science, so you might want to check that one out first. Also, there are quite a few of us who are interested in Mathematics, I am one of them, who would gladly help out with anything specific.

I got a 2.2 in my degree, but I was never too serious in my maths degree. I managed a 2.1 in my physics degree, that proves I was less dim!!!!! I am doing my third degree, in life sciences, and really want a first!

The maths link and the videos from MIT look very helpful thanks allot both of you :D

One thing that is on my mind is what exactly is "Vector Projection" in relationship of 2D physics. From my understanding it is a direction that expands infinity as a line but I don't think I am correct :laugh:

I am amazed that you do not get maths! It is a) so easy and b) so simple. Here is a simple easy maths primer... here[^]

I googled and found this page, which explains a vector projection simply enough. Seems like you just place two vectors at the same origin. You then create a triangle by connecting the tip of one to the side of the second using a line perpendicular to the second (so a triangle with one 90 degree corner). Take the vector created by connecting the origin to that point on the second vector where the perpendicular line connects, and you have your vector projection. I am not sure what it is used for in 2D physics.

I (easily) passed the courses Graphics (50% of it was linear algebra), Data-structures (mostly about algorithmic complexity) and even Cryptography without passing the 1st-year Maths course (not until I re-did it for the 3rd time). Knowing a lot about maths may not be as important as they want you to think..

Sadly I have looked there, just seems to be too much association with maths terms I am not familiar with ie: "The vector resolute (also known as the vector projection) of two vectors, A in the direction of B (also A on B")" ... tells me that a projection is a direction between two vectors... The math symbols used some of which I know (dot product for example I know returns a number representing a vectors direction ie 0), but make it hard for me to just look at and understand :(

I presume you un univoted me. Thanks But really, how hard is sums? Look it is all just algebra and functions, and once you get that then all is clear.

That is all I needed to figure it out! :-D

I could swear I did the first time around! Rectified.

I don't find them hard, but some were quite tedious. Some of the expansions and transforms that we did back in school.. a recipe for a headache. However, when I first tackled my MS degree, I was dumbstruck by how much harder it was for me to do, what I previously considered simple, calculus. I am certain it was due to my lack of practice.

I clicked the thumb up though like all comments so far :doh: You deserve a 5 I am trying to click them and it appears to be working.

Ultimately, what it means is that a vector projection is nothing more than the compound of two vectors. An analogy. Two billiard balls approaching each other. Upon collision, if we were to consider only one of them, what is the new vector it results with, due to the impact, starting at the point of impact. Easy, eh? :)

All modules at 'just passed' except the finals, which were boosted by the oral digression and the essays. My finals were a little bland and normal, I feel I am far better at physics than my degree shows, but I can't prove it.
