# Casio ClassPad II fx-CP400 Calculator User Guide

Equipped with a high resolution 4.8 inch large touch-panel LCD, the fx-CP400 provides clearer images of mathematical data for students, as well as a better way to comprehend the relationships between their equations and graphs since the calculator can display both at the same time. Also, with the touch of a button, the fx-CP400 can switch from a vertical view to a horizontal view, which is convenient for displaying long mathematical formulas on a single line. Both of these capabilities make it easier for students to grasp difficult mathematical concepts.
