Beautiful 4.8-inch color display
Formulas, graphs, and other graphics are sharp and clear.The display has resolution of 320 x 528 pixels (more than 65,000 colors), 4.4 times higher than ClassPad 330 PLUS.
Quickly and easily create graphs using drag and drop.
Touch-panel operation by stylus or finger
The fx-CP400 offers intuitive stylus touch-panel operation that eliminates complicated key operations. Graphically display mathematical formulas by simply dragging and droppingthem into the graph area.
Create a graph by selecting a formula
and using drag and drop.
Brand-new software keyboard
Computer Algebra System (CAS)
The CAS supports everything from Expand, Factor, Solve, and other basic commands to advanced commands like Fourier and Laplace transforms.
Graph & Picture
Select the formula for the graph you want to create.
A graph screen with a visual appropriate for creating a graph of the selected function is displayed.
Congratulations! Your graph is complete.
Change the graph by repeatedly changing coefficient to create a graph that visually matches the parabola.
