Math Help: Improve Skills, Grade 80%, Vector Spaces

In summary: You should also consider looking into online courses or MOOCs. They're a lot cheaper (though you have to put in the time to learn) and you can get a certificate or a degree from some of them.

OK I got my overall final grade in Calculus II. It is pretty low, only 80% and really made me want to blame myself for not really studying on my finals because I had a bunch of work to do the week after. I studied for many hours the day after, but it is really bad idea for me to study the day after the exam.

Now, there are no more math offered for my course. I want to know how to improve my skills in math? Should I step backward and study college algebra again or move to the next? But what is that? Currently, I'm studying linear algebra and I'm on the vector spaces topics.

btw, is 80% grade pretty low? I'm so worried that I might not get into computer graphics research on this kind of grade.

This is actually a good idea, the most important thing is to understand what you did wrong so that you learn it for the later courses.

It's a b/b-. That's fine. Not terrific, but not hideous. What aspect of graphics work are you doing? For the most part calc II doesn't even matter, linear algebra is much more important in graphics work.
My experience with undergrad research is that if it's at your school, the professors don't ask for grades. They want to know that you've taken enough comp sci and math to be useful, that you're fairly competent, and that you're motivated. Helps if you stand out enough that they ask you to work for them/let you work for them.

I studied for many hours the day after, but it is really bad idea for me to study the day after the exam.
as long as you study before the exam, the more review of the material the better. Math is one of those subjects you only get better at by doing a zillion times.

Computer graphics makes use of a lot of math. Triangle rasterization uses calculus. Coordinate system transformations use linear algebra. If you want to write a good geometry engine then geometry beyond your standard euclidean stuff will be required: things like convex hull voronoi diagrams, barycentric coordinates, heaps of stuff.

If you are going to do work with bezier curves or surfaces or even NURBs you will need to know multivariable and vector calculus well enough. This is also true for understanding
how basic lighting works.

If you are modelling light then radiosity and raytracing will be your friend if you're doing things like in say a pixar movie.

BSP trees make good use of euclidean geometry where splitting planes need to be identified.

You can learn computer graphics in a plug and chug way but if you are going to be really good at it, you need to understand the underlying math and the math extends beyond what you will find in an introductory calculus course.

Theres a lot of books like the Graphics Gems series books that don't shy away from the math required.

It's not after, it's before. lol

Anyway, I remembered I told to myself last semester on my calculus 1 class that I really want to get 95% on my next class but I definitely failed. The exam is really easy except for the 3 problem. The first and second one is in trigonometric integrals and the third is in 1/(sqrt(function))^(function). And they are both 10 points each which will definitely fail to get a 80+ score.

Now, I'm thinking on studying again my algebra. I don't if this the best way but is there any more advance level of algebra? I heard there's a algebra 2 but I don't have that class on my curriculum. The last math is this, calculus 2. It really sucks here in asia.

Yeah, that's why I'm studying linear algebra first. Most of the people in gamedev.net told me that I should really know linear algebra first then move to vector calculus and more advanced concept to help me in 3d graphics. Others told me that I should study multivariate calculus first because that's the pre-requisite of linear algebra. But I try to get into linear algebra first and found no calc 3 concepts inside. Or maybe I'm wrong.

So what should I do now to improve my math skills without any math class in the university?
 

Related to Math Help: Improve Skills, Grade 80%, Vector Spaces

1. What are vector spaces in mathematics?

Vector spaces are mathematical structures that consist of a set of objects, called vectors, which can be added together and multiplied by scalars (usually real or complex numbers). These operations must follow certain rules, such as closure and associativity, to be considered a vector space.

2. How can I improve my skills in math?

One way to improve your skills in math is to practice regularly. This can include solving problems, completing exercises, and working through examples. Additionally, seeking help from a tutor or teacher can also be beneficial in improving your understanding of concepts.

3. What is the importance of improving my grade in math?

Improving your grade in math can open up opportunities for higher education and future careers. Many fields, such as science, engineering, and finance, require a strong foundation in math. Additionally, having a good grade in math can also improve critical thinking and problem-solving skills.

4. How can I reach a grade of 80% in math?

To reach a grade of 80% in math, it is important to consistently practice and review material, seek help when needed, and actively engage in class. It may also be helpful to break down complex problems into smaller, more manageable steps, and to check your work for errors. With determination and effort, an 80% grade is achievable.

5. Is it possible to improve my grade in math even if I struggle with it?

Yes, it is possible to improve your grade in math even if you struggle with it. It may require extra effort and seeking help from a tutor or teacher, but with consistent practice and determination, anyone can improve their understanding and grades in math.
