Inputting and Editing Calculations

uUsing the MATH Menu

In the RUN MAT mode, pressing 4(MATH) displays the MATH menu.

You can use this menu for natural input of matrices, differentials, integrals, etc.

{MAT} ... {displays the MAT submenu, for natural input of matrices}

{22} ... {inputs a 2 2 matrix}

{33} ... {inputs a 3 3 matrix}

{mn} ... {inputs a matrix with m lines and n columns (up to 6 6)}

{logab} ... {starts natural input of logarithm log ab}

{Abs} ... {starts natural input of absolute value X}

• {d/dx} ... {starts natural input of linear differential
