HL 2.7 - Solving modulus equations & inequalities
HL 2.16: Solution of modulus equations and inequalities Absolute value (modulus) equations and inequalities occur frequently in mathematical analysis. Unlike many equations, solving modulus equations relies as much on reasoning and visualizing (sketching a graph) as algebraic methods. For this reason, it is important to look specifically at these types of equations and inequalities. There are several approaches to...
