SUsing the MATH Menu

In the RUN • MAT mode, pressing (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}

•{2σ2} ... {inputs a 2 × 2 matrix}

•{3σ3} ... {inputs a 3 × 3 matrix}

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

•{logab} ... {starts natural input of logarithm logab}

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

• {d/dx} ... {starts natural input of linear differential		d	f(x)x = a }
		dx
				2
• {d2/dx2} ... {starts natural input of quadratic differential				d	f(x)x = a }
				2
