For questions about vector spaces and their properties. More general questions about linear algebra belong under the [tag:linear-algebra] tag. A vector space is a space which consists of elements called "vectors", which can be added and multiplied by scalars. In other words, these are the spaces ...
I solved a linear mapping problem recently and it turns out no to be correct, although i thought it was a simple problem. The problem asks me to find real parameters $a,b,c$ such that linear mapping ...
