This student-friendly text clearly integrates microeconomic theory with calculus and graphics; its approach centers on constructing and analyzing fundamental models. By integrating basic tools of calculus, the text encourages students to solve problems by generating actual numerical solutions. The manner in which calculus reinforces the graphical analysis is clearly demonstrated in a step-by-step fashion; students will understand what the graphical solutions actually represent. Numerous real world applications of the theory are highlighted throughout the text.
