Question about Texas Instruments TI-89 Calculator

Ad

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on. Turn the calculator on (or at least press the ON key). Press and hold the 2ND key, then repeatedly press the + key and see whether the display lights up. If you go too far, use the 2ND and - keys.

The calculator does not have a TVM application, so you cannot perform these calculations.

There is no such key on this calculator. You can calculate it using factorials. To calculate nCr you can calculate n! / (r! * (n-r)!).

To calculate the natural logarithm of a number, enter the number and press the LN key. To calculate the natural logarithm of a calculated result, simply press the LN key.

To calculate the natural logarithm of 3, press 3 LN

To calculate the logarithm to any other base, calculate the natural logarithm and then divide by the natural logarithm of the base.

To calculate the base-10 logarithm of 3, press 3 LN / 1 0 LN =

On Windows based computers you already have a calculator. Look for it under Start>All programs>Accessories>.

Also, with Windows based systems, you can download (free of charge) Microsoft Mathematics 4. Launch a Google search. Download the version compatible with your operationg system (32 bits or 34 bits)

Using the Windows calculator in scientific view, we get:

17^23 = 19,967,568,900,859,523,802,559,065,713

which is 29 digits long, ie much longer than the capacity of most calculators.

Because both 17 and 23 are prime numbers, it isn't possible to simplify this calculation, so you will need to use find a calculator that has sufficient capacity to be able to handle numbers of this length.

The*xnumbers* add-in for Microsoft Excel can also be useful for this sort of calculation (do an internet search for it).

Using the Windows calculator, MOD55 of the above number is 18.

The [MODE] key can be used to select the modes described below.

Important! The following is a general explanation of Scientific Calculator modes. Note that your calculator may not include all of the modes described here.

1) Calculation Modes

Before performing a calculation, you first need to select the appropriate calculation mode.

COMP: Basic arithmetric calculations

(arithmetic operations, trigonometric functions, etc.)

COMPLEX: Complex number calculations

SD: Single-variable statistical calculations

(sample standard deviation, etc.)

LR or REG: Paired-variable statistical calculations

(linear regression statistical calculations, etc.)

BASE or BASE-n: Binary, octal, decimal, hexadecimal number system calculations

MAT: Matrix calculations (determinants, etc.)

VCT: Vector calculations

EQU: nth degree equations, simultaneous equations

2) Display Settings

Use these settings to control how calculation results are displayed.

Note that changing the Fix and Sci settings does not affect internal calculation results.

Norm: Exponential display format and cancels the currently configured Fix and Sci settings.

Fix: Specifies a fixed number of digits to the right of the decimal place.

Sci: Specifies a fixed number of significant digits.

3) Angle Unit Setting

(90°=?/2 radians=100 grads)

Deg: Degrees

Rad: Radians

Gra: Grads

4) Engineering Mode

Use this mode when you want to input and perform calculations using engineering symbols.
