Sarahisme Posted May 2, 2005 Share Posted May 2, 2005 hows this.... 7a) Since the vectors are not multiples of eachother therefore they are linearly independent. b) it must be a linear combination of the two vectors. and the condition b4 - b1 = 0 has to hold. so am i completely wrong? :S Sarah Link to comment Share on other sites More sharing options...
Dapthar Posted May 2, 2005 Share Posted May 2, 2005 7a) Since the vectors are not multiples of eachother therefore they are linearly independent.Yup.b) it must be a linear combination of the two vectors.Yup.and the condition b4 - b1 = 0 has to hold.This is redundant, since if the vector in question is a linear combination of the two basis vectors, this relation is automatically satisfied.

Sarahisme Posted May 2, 2005 Author Share Posted May 2, 2005 oh ok yeah thats makes sense. thanks once again Dapthar Link to comment Share on other sites More sharing options...
Sarahisme Posted May 3, 2005 Author Share Posted May 3, 2005 umm one thing..... i think the question is asking for a bit more detail that is.... for part b) should i say the conditions that b must satify is ....(well i think there is only one...) b4 - b1 = 0 Link to comment Share on other sites More sharing options...
