- Let T:R3R3 be the linear transformation that projects u onto v=(2,1,1). (a) Find the rank and nullity of T. (b) Find a basis for the kernel of T.arrow_forward14. Let be a ring with unity . Verify that the mapping defined by is a homomorphism.arrow_forward12. Consider the mapping defined by . Decide whether is a homomorphism, and justify your decision.arrow_forward
- Let T be a linear transformation T such that T(v)=kv for v in Rn. Find the standard matrix for T.arrow_forwardExpress the given linear mapping w = f(z) as a composition of a rotation R(z), magnification M(z), and a translation T(z). Then describe the action of the linear mapping in words. f(z)=(-1/2)z+1-sqrt(3)i i is not under square rootarrow_forwardConsider polynomials with degree less than or equal to n. We can think that each polynomial p(x)=a+a,x+...+a,x" is a vector in the n+1 dimensional vector space, with components (a.a,,a,) and basis (1.x,...,x). Find the representation of the space. d operator in this vector dxarrow_forward
