where F^(infinity) denotes the vector space consisting of all sequences of elements of real or complex numbers.
Answer : Assume that F has dimension n, which is a finite positive integer. Let a1 be the sequence starting with a 1 and all the other terms 0. Let a2 be a sequence of all zeros except the second term, which is 1. ... Let an be a sequence of all zeros except the n-th term, which is 1. Clearly, are linearly independent.
Now let's construct a sequence a(n+1) with all terms 0 except the (n+1)st, which is 1. Now, it's impossible to arrive at a(n+1) as a linear combination of , thus, the vector space cannot be n-dimensional for any positive integer n (proof by contradiction).
To Theodore: it can be proven that all vectors of an n-dimensional vector space can be written as linear combinations of ANY of the possible bases, so it follows that if a vector cannot be written as a linear combination of some basis then no other basis with n elements works.

Question : How do you resolve three dimensional vectors?
Eg. [N 33 degrees E 44 degrees U]
Answer : I assume there is a comma between E and 44 and U means up Let V be the magnitude of the vector. i, j, k are unit vectors in x, y, z directions respectively The vector's projection in the x-y plane is Vcos44 90-33=57 That projection has components Vcos44[cos57 i + sin 57 j ] The projection of the vector on the z-axis is Vsin44 k So adding it up you have V{cos44*cos57 i + cos44*sin57 j + sin44 k }
