*1 Mixed fraction is supported in the Math input/output mode only.

*2 For information about function input from the MATH function menu, see “Using the MATH Menu” described below.

*3 Tolerance cannot be specified in the Math input/output mode. If you want to specify tolerance, use the Linear input/output mode.

*4 For Σ calculation in the Math input/output mode, the pitch is always 1. If you want to specify a different pitch, use the Linear input/output mode.

*5 This is the number of bytes for a 2 × 2 matrix.

uUsing the MATH Menu

In the Run-Matrixmode, pressing 4(MATH) displays the MATH menu.

You can use this menu for natural input of matrices, derivatives, 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 logab}

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

{d/dx} ... {starts natural input of first derivative dxd f(x)x = a}

• {d2/dx2} ... {starts natural input of second derivative

d2

f(x)x = a}

dx2

• {dx} … {starts natural input of integral ab f(x)dx }

 

 

 

β

• {Σ(} … {starts natural input of Σ calculation Σ f(x) }

x=α
