11 Natural logarithms and the power of E on the calculator

Natural logarithms, like , can be assessed using your calculator using keys. For example, the key. The other function of this key ( ) allows the calculation of power of . It is important to note that an approximate value for the key itself is found by using the key sequence ( ).

Keep in mind that is the same thing as. Certain calculators come with a key in place of .

20. Calculating natural logarithms and the powers of E

Determine the value of each of these with your calculator, giving the answers to 3 important figures.

Find the answer

12 Calculator reference guide

Calculator uses various modes

General modes

The calculator is able to operate in a variety of different modes:

  • COMP, which is used to do general calculations.
  • STAT is utilized for statistical calculations.
  • TABLE, which is used for generating tables of numbers.

COMP is the abbreviation for 'computation while STAT is the abbreviation for'statistics'..

The Comp mode can be selected the use of the keyboard sequence (COMP).

Mathematics-related modes

There are two ways to input maths applied to and displayed by the calculator:

  • Math mode, where fractions are entered and displayed in their mathematical forms For instance, - and some irrational numbers can be displayed in surds (such as ) or multiples of (such as ).Math mode is set by making use of the keyboard sequence (SETUP) (MthIO).
  • Linear mode, in which fractions such as are entered and displayed using a linear notation - for example, 2 3 - and all irrational numbers (such as and ) are displayed as decimal approximations.Linear mode is selected by using the key sequence (SETUP) (LineIO).

Put simply, an irrational number is one which cannot be expressed as a simple fraction.

You will know you're in Math mode if the word Math is shown near the right-hand display at the top calculator display. If it's not that means you're in Linear mode.

In Math mode, you can force the answer to display in decimal form , or switch between the mathematical and decimal outputs using .

Fraction display modes

The calculator can set the calculator so that answers that are top-heavy fractions (such for ) is shown with mixed numbers (such like ).

  • To set the calculator to display mixed numbers, you must use the sequence key (SETUP) (ab/c).
  • To set the calculator to display top-heavy fractions, use the sequence key (SETUP) (d/c).

Decimal display modes

The calculator can be configured to display decimal numbers in several different ways:

  • Normal 1 (Norm 1) mode makes use of scientific notation for numbers less than 0.01 but greater than -0.01 in other cases, and also displays answers according to the decimal spaces they contain in the limit that will fit on the display. This mode can be accessed via (SETUP) (Norm) .
  • Normal 2 (Norm 2) mode uses scientific notation for any number smaller than 0.000000001 but larger than -0.000000001 but it still displays answers to however many decimal places they are with the exception of the maximum number that is possible on the screen. This mode is activated using (SETUP) (Norm) .
  • Scientific notation mode (Sci) displays every decimal number in scientific notation using the number of significant figures. This mode is activated using (SETUP) (Sci) followed by the number of significant figures to be used, for example . When you are using your calculator is in this mode the display indicator SCI appears shown.
  • Fixed decimal-place Mode with fixed decimal places (Fix) displays every decimal number to an appropriate the number of decimal decimal positions (unless some scientific terminology is required to make the results fit on the screen). This mode is activated by using (SETUP) (Fix) followed by the number of decimal places needed, for instance . If you are using your calculator is in this mode, the display indicator FIX will be displayed.

12.1 Display indicators

The symbols are displayed upon the calculator display to indicate the status at present.

Symbol on display Meaning
This key was held.
A key was pressed.
M A value is saved in the memory called 'M'.
STO The STORE key ( (STO)) is held.
RCL The RECAL ( ) key was pressed.
The calculator is designed to measure angles in degrees.
The calculator is configured to measure angles measured in radians.
The calculator is designed to measure angles in gradians.
FIX The calculator will display answers to a certain amount of decimal points.
SCI The calculator will provide results in scientific notation and some fixed numbers of relevant figures.
Math This calculator can be set to utilize Math mode for data input, and for display.
STAT The calculator is in statistics mode.
There is more information available that can be displayed and it can be accessed through the up and down keys.
The line that is displayed is much longer than it can be displayed on the display. Other lines are shown by scrolling the left and right mouse keys or .

12.2 Common operations

To Key sequence
Turn on
Turn off (OFF)Note in that calculator will turn off automatically if not used for about 6 minutes.
Set the display's contrast. (SETUP) () Then use the settings and adjust, and press once finished.
Restore factory settings (CLR) (Setup) (Yes)
Clean out all memories (CLR) (Memory) (Yes)
Restore the default settings and erase any memory (CLR) (All) (Yes)
Make a calculation unchangeable, or exit menus
Find an answer
You can get a decimal result in Math mode
Switch between decimal and exact solutions in Math mode
You can toggle between showing fractions as improper fractions or mixed numbers in Math mode
Make use of the results of earlier calculation...
... e.g. to find 42 minus the previous result.
Write a value into memory with the letter 'M' (STO) (M)
Clear a value stored in the M memory (STO) (M)
Input a value in the memory of 'M'
Subtract a value from that in memory 'M' (M-)
Display the value stored in the memory 'M'. (M)
Make use of the memory "M" in the calculation...
... e.g. to find 42 minus the value in the memory 'M' (M)
The angles that are to measure in degrees (SETUP) (Deg)
Measure angles in radians (SETUP) (Rad)
Set the answers to be displayed to 3 decimal places (To choose a different number of decimal decimal places, replace with the number) (SETUP) (Fix)
Set answers to be presented in scientific notation and three significant figures (To utilize a different number of significant figures, replace this number) (SETUP) (Sci)
Removing any setting for rounding the display (SETUP) (Norm)

The A B, C D, X Y memories are used in the same manner as those of the M memory, except they do not have subtracting or adding from' functions.
