    How Do You Graph the Complex Function w = z^(i+2)?

    For example : z={z|0<=arg z<=(pi)/6} Draw w=z^(i+2). I can draw w=z^2 and w=z^i But w=z^(I+2)is a holy garbagety

    The relation between span(In,A,A2, )and it's minimal polynomial

    y,but i don't know why can't I write A in span{A2,I}? I'm sorry about the type..

    The relation between span(In,A,A2, )and it's minimal polynomial

    Let A ∈ Mn×n(F ) Why dim span(In, A, A2, A3, . . .) = deg(mA)?? where mA is the minimal polynomial of A. For span (In,A,A2...) I can prove its dimension <= n by CH Theorem but what's the relation between dim span(In,A,A2...)and deg(mA)
