How to Use the Function Graphing Calculator

Using the graphing math calculator is intuitive and fast:

1. Enter the function: build Y1 with the on-screen keys, using the X,θ,T key for the variable 'x' (example: sin(x), x^2+3*x-5, log(x))
2. Add to graph: press EXE (or F3) to display the function on the Cartesian plane
3. Move the view: use the d-pad arrows to pan the graph window
4. Use zoom: the F2 (Zoom) key magnifies the graph 2x around the origin
