randIntNoRep(

randIntNoRep( returns a random ordered list of integers from a lower integer to an upper integer. The

list of integers may include the lower integer and the upper integer. Numtrials is optional and lists the

first numtrials in the output.

randIntNoRep(lowerint, upperint, [numtrials])

ANGLE Operations

ANGLE Menu

To display the ANGLE menu, press y;. The ANGLE menu displays angle indicators and

instructions. The Radian/Degree mode setting affects the interpretation of ANGLE menu entries.

Note: Use Catalog Help for more syntax help when needed.Select a menu item and then press Ã to go

to a syntax help editor (if the menu item is supported).

Entry Notation

DMS (degrees/minutes/seconds) entry notation comprises the degree symbol (¡), the minute symbol ('),

and the second symbol ("). degrees must be a real number; minutes and seconds must be real

numbers ‚ 0.

Note: DMS entry notation does not support fractions in minutes or seconds.

degrees¡minutes'seconds"

For example, we know that 30 degrees is the same as p/6 radians, and we can verify that by looking at

the values in degree and radian modes. If the angle mode is not set to Degree, you must use ¡ so that

the TI-84 Plus C can interpret the argument as degrees, minutes, and seconds.
