Best ResponseYou've already chosen the best response.0It's hard to tell exactly since you haven't defined what P is. I'm assuming it's a polynomial? I'm also thinking the subscript is the big giveaway re. dimension. \[\dim(P_n)=n\]\[\dim(P)=1\]\[\dim(P_3)=3\]...if I had to take an educated guess.

Best ResponseYou've already chosen the best response.0hi Lokisan, thanks for the reply...I was going through the following link http://tutorial.math.lamar.edu/Classes/LinAlg/Basis.aspx and my guess is that dim(Pn)=n+1 dim(P)=1 and dim(P3)=4 I dont know even my prof did not define what p is...may be I have to go around basis and linear independence and try to get the dimension....can u tell me if am thinking in the right direction...

Best ResponseYou've already chosen the best response.0Sorry  I did mean to put dim(P_n)=n+1 etc.

Best ResponseYou've already chosen the best response.0If they are polynomials, then it's the case\[\dim(P_n)=n+1\]

Best ResponseYou've already chosen the best response.0It will depend on the convention for subscripting on the polynomial.

Best ResponseYou've already chosen the best response.0I would say,\[\dim(P_n)=n+1\]\[\dim(P_3)=4\]and as for \[\dim(P)\]if you're to take the subscript as 1, then the dimension is 2, and if the subscript is taken to be 0, then the dimension would be 1.

Best ResponseYou've already chosen the best response.0Is there any subscript on problem 2?

Best ResponseYou've already chosen the best response.0nope...it was written the same way in my class...may be i put it as how u told...like 1 if the subscript is 0 and 2 if the subscript is 1....i think that shud be fine...isnt it so...

Best ResponseYou've already chosen the best response.0Oh, okay, if it's a written submission, I would do that. I was just worried in case it was something you had to submit online.

Best ResponseYou've already chosen the best response.0You should probably check with your professor about the convention before submitting. No point losing marks for nothing.

Best ResponseYou've already chosen the best response.0Good. Just thinking, you might want to check out the MIT lectures on YouTube. They also provide examples which can be helpful. I haven't checked them out for vector spaces, but I think it's worth a try. The examples I've seen on other topics are quite good.
