linear transformation

let V be a real n-dimensional vector space and let T:V-->V be a LT saisfying T(v)= - v for all v belongs to V.
1. show n is even
2.use T to make V into a cmplex vector space such that the multiplication by complex numbers extends the multiplications by real numbers
3. show that with respect to complex vector space structure on V obtained in 2. , T is a complex linear transformation

Have you left something out? This statement does not follow from just what you have stated.

PS: I found your mistake. You want T2(v)= −v for all vV.

Re: linear transformation

I have no idea about the answer. But the question is correct.

Re: linear transformation

Ops! Sorry........ Yes I wanted T2(v)= −v
