comment Prove well-definedness of comultiplication and counit of $GL_q(2)$ and $SL_q(2)$.
Sincere thanks! I don't get how Kassel computes $\Delta (det_q-1)$ though. Also, I don't really understand coideals. (my background is undergraduate, with highest level course being introductory galois theory)

comment minimal polynomial and monic characteristic polynomial
Does that follow from the definition $T_\beta(k):=\beta k$?

@MichaelGreinecker You are right (+1), the instructor didn't reference the exercises even though he did indeed take the questions from some source, with very minimal modifications.
