4. Calculations Using MATH Menu Items

The MATH menu contains functions used for more elaborate math concepts, such as trigonometry, logarithms, probability, and math unit/format conversions. The MATH menu items may be incorporated into your expressions.

Note: The default angle measurement unit while using the calculator’s Basic Keyboard is degrees. If you wish to work in radians, then the configuration must be changed in the SET UP menu. For more information, see page 25.

A Note about

The degree and radian systems are two of the basic methods of

Degrees and

measuring angles. There are 360 degrees in a circle, and “2-pi”

Radians

radians. 1 degree is equal to pi/180 radians. “Then, what’s this

 

pi?”, you may ask. Pi, or to use its symbol “π”, is the ratio of the

 

circumference of a circle to its diameter. The value of π is the

 

same for any circle “3.14...”, and it is believed to have an infinite

 

number of digits beyond the decimal point.

 

A CALC

 

The CALC sub-menu contains items to be used in calculations

 

containing trigonometric and logarithmic functions.

Note:

The following examples show keystrokes with keyboard shortcuts.

 

It is also possible to select a sub-menu item using the cursor

 

keys.

1sin Enters a sine function to be used in a trigonometric calculation.

Example

•Calculate sine 90°.

MA19 0 E

2cos Enters a cosine function to be used in a trigonometric calcula- tion.

Example

•Calculate cosine 60°.

MA26 0 E
