While determinants are taught early in mathematics, university algebra introduces them via permutations and cofactor expansions.

Take a solved problem and (e.g., "Prove G is abelian" → remove "abelian" and try to prove a weaker result). Compare with original solution. This trains you to see why each hypothesis is necessary. Published by New Age International , it provides
Let T: R^3 → R^3 be defined by T(x,y,z) = (2x + y, x – 3y, z). Find the matrix of T relative to the basis B = (1,0,0), (1,1,0), (0,0,1). Then compute T^2(v) for v = (1,2,3) using the matrix power.
Direct and simple presentation that avoids irrelevant details to focus on core concepts. About the Author z) = (2x + y
