Question

Can anyone give me an example of an endomorphism of a vector space?

Answer 1

Is this calculus?

Answer 2

Linear algebra in this case, but there seem to be other kinds of endomorphisms. I probably should have been more specific.

Answer 3

Ah, whats the difference between linear and regular algebra?

Answer 4

A lot, it's pretty hard to explain.
Linear algebra has to do with vectors, matrices, things like that. You probably don't know those terms though, but you will meet them soon enough.

Answer 5

Ok :D

Answer 6

this one maps to itself. L:V->V

Answer 7

I know that, I wanted an example of one that is actually used specifically.

Answer 8

Ok, say V is in R3. Let L be a 3x3 matrix and L takes V into V

Answer 9

for R2 the matrix
| cos x -sin x |
| sin x cos x|
rotates a vector in R@2

Thanks
