    EQN : Use this mode to solve simultaneous linear equations with two or three unknowns. TABLE : Use this mode to display a defined function in a tabular form. VERIF : Use this mode to perform the numerical comparison and check. PROP : Use this mode to perform ratio expression calculations.

  • Page 7: Using Math Mode

    CONT : Contrast Adjustment Using Math Mode Press [ 2nd ] [ SET UP ] [ 1 ] to enter Math mode. While in math mode, the values for functions such as , log b, Abs, 10 − , √ , ..can be entered and displayed in a mathematically written way.

  • Page 8: Memory Calculation

    You can continue moving the cursor by [ ] or [ ] to display previous input steps and editing values or commands for subsequent execution. See Example 4. The operation records in Memory are cleared each time when you turn off the calculator, press [ ON ] key, perform a “reset”, change display format or calculation mode.

  • Page 9: Order Of Operations

    Order of operations Each calculation is performed from left to right and in the following order of precedence: Expression inside parentheses. Functions with parentheses: P R, R P, PPCM, PGCD –1 –1 –1 –1 sin, cos, tan, sin , cos , tan , sinh, cosh, tanh, sinh –1...

  • Page 12: Parentheses Calculations

    –9 Results equal to or greater than 10 or results less than 10 displayed in exponential form. See Example 9. Parentheses calculations Operations inside parentheses are always executed first. The calculator Math mode can use up to 24 levels and Linear mode can use up to 25 levels of consecutive parentheses in a single calculation.

  • Page 13: Answer Function

    Answer Function Answer function stores the most recently calculated result. It is retained even after the power is turned off. Once a numeric value or numeric expression is entered and [ M+ ], [ 2nd ] [ M– ], [ RCL ], [ 2nd ] [ STO ] or [ = ] is pressed, the result is stored by this function.

  • Page 14: Angle Unit Conversions

    (Note) : 1. “ ” next to the resulting fraction signifies that the fraction is not yet in simplest form. 2. “Fraction irreduc” appears that further simplification is impossible. Angle unit conversions The angle unit (Deg, Rad, Grad) is set by pressing [ 2nd ] [ SET UP ] from Setup screen and results are displayed according to your setting.

  • Page 15: Coordinates Transformation

    Coordinates transformation Rectangular Coordinates Polar Coordinates x + y i = r (cos θ + i sin θ ) (Note) : When using those keys, make sure the calculator is set for the angle unit you want. The calculator can perform the conversion between rectangular coordinates and polar coordinates by [ 2nd ] [ P R ] and [ 2nd ] [ R P ].

  • Page 16: Using Calc

    Using CALC CALC function lets you temporarily store a mathematical expression that contain variables, which you can then recall and execute in the COMP Mode. The following describes the types of expressions you can save with CALC. See Example 38. Expressions: 2X + 3Y, 2AX + 3BY + C Multi-statements: X + Y : X (X + Y) Equalities with a single variable on the left and an expression...
