    Understanding Basis for Solving Linear Algebra Problems

    Thanks guys. Anyway I just did my linear exam today so hopefully I never have to see linear ever again!

    Understanding Basis for Solving Linear Algebra Problems

    Hey guys There are so many of these damn "Find a basis" questions and I can't get any of them because we never directly learned how...or she never showed us in class...my final exam is tomorrow. Here are some examples of questions: http://184.154.165.18/~devilthe/uploads/1323453294.png...

    Two linear algebra questions - Vector geometry

    No we have not...I saw that on another site as an answer to this question but had no idea how they got the answer.

    Undergrad When to Solve for dimH vs. Column Space or Null Space?

    Thanks for your help I pretty much get it now. But in the second question I only see her solving for the dim of the null space and not looking @ the rank or dim of the column space as you said (I understand why you would do that now). Here's a pic of it in my notes...

    Undergrad When to Solve for dimH vs. Column Space or Null Space?

    I forgot to say that the matrix they give is called H. I edited my first post.

    Undergrad When to Solve for dimH vs. Column Space or Null Space?

    Hi guys So I'm studying for my test tomorrow and I understand how to find the dimensions of ColA and NulA, but what I don't understand is when they give you for example a matrix H, and then they just say Find dimH. What am I suppose to be solving for? We did two examples in class and in one...

    Undergrad Trouble understanding spans of vector spaces

    Yea sorry that's what I meant to say! Basis not span! Yes what you said did help but I still do not understand how to know whether or not a set of vectors given is a span or not. Like saying a basis is a 'linearly independent spanning set'. How do you know the spanning set part?

    Undergrad Trouble understanding spans of vector spaces

    Hey guys So the problem I'm having here is spans! I know that a basis of a vector space is a linearly independent spanning set So the linearly independent part is pretty easy...looking at whether or not vectors are linear combinations of the others (right? Or do I have to look at it by...

    What Caused This Unusual Rock Formation?

    Great thanks so I'm pretty much done my report I just have one more question. This is the 2nd stop we saw after seeing the picture in my FIRST post. I haven't posted this before but I now have questions baout it and it could help you with understanding the depositional environment...

    What Caused This Unusual Rock Formation?

    True, but I'm going on the basis that the Mount Royal area had some igneous activity in the past. Also the highest rock is also igneous... Am I going on the wrong path here or what? I need to write what the depositional environment was at the time but I'm quite lost!
