For any complex number a+bi, the absolute value is the sqrt(a^2+b^2). In your example,
a=7 and b=-1
a^2=49; b^2=1
so a^2+b^2=50
sqrt(50)=5*sqrt(2)

How can I find the mean absolute deviation?


Mean absolute deviation.
Let's break it down into its components.
Mean - Average
Absolute - absolute value - sign doesn't matter - if negative, make positive
Deviation - difference from the mean

Let's do an example. Population 3 7 4 2. Total 16. Mean (Average) 16/4 = 4.

Deviations
3 - 4 = -1 absolute value 1
7 - 4 = 3
4 - 4 = 0
2 - 4 = -2 absolute value 2

Sum of these deviations 1 + 3 + 0 + 2 = 6
Mean (average) of these deviations is 6 / 4 = 1.5.

Good luck,

Paul

What is mean absolute deviaton of these numbers: 45,35,23,37,29,53,43?


Calculate the average of these numbers (mean), then the difference between each number and the average, add the absolute value of these differences and divide by the total number of data (here 7)

Anyone know how I can do Absolute Value on this?


The quick way to determine absolute value is to square the value and take the square root of that.
So on the TI, with the value on-screen, just push these 2 keys in sequence (they are right next to each other):

Complex matrix


Is it complex or matrix? You can have only one mode at a time.What kind of equations? The solve function uses real-valued equations.
Complex numbers: You can add, subtract, multiply and divide. You can convert a number from rectangular to polar forms and vice-versa; you can calculate the absolute value of a complex number, or a conjugate.
All the operations are done in the Mode CMPLX.

Error when converting complex numbers to fraction form With mode in a+bi form, when dividing two complex numbers, the answer is displayed in decimal form. The old operating system would allow the decimals...


Not quite true for OS 2.56 MP for the TINspire with Ti84 keyboard. To convert a complex decimal value, that you just calculated, into a fraction use the command Math [1:>Frac] and it will convert the value to complex fractions
See below.

How do you use the i function. My teacher couldnt find it and we are doing imaginary numbers so i realllly need to know


Turn calculator ON.
If you see no icons, press [MENU] key.
Use Arrows to focus on RUN and press [EXE]
Press [OPTN]
Among the TABS that appear at the bottom of screen you have CPLX.
Press [F3] to activate it.
The menu TABS that are displayed allow you manipulate complex numbers:
F1 :i imaginary unit i
F2: Abs takes the absolute value of a complex number.
F3:Arg, gives the argument (angle the complex number makes with the positive X-Axis)
F4: Conj calculates the Conjugate of a number.
F5: ReP extracts the Real part
F6:Imp extracts the Imaginary part.

For other operations use the operation keys [Plus] [MINUS] [*][/] [X^2] [Square root]. Be careful using the universal power key or the xroot key as it may lead to a Memory error.

How do you determine absolute value on a TI30XA calculator?


If you are looking for a key, there is none. However, you can still determine the absolute value easily.
  1. If you have a single number and its positive, the absolute value is the number itself.
  2. If you have a single number and it is negative, just drop the leading minus sign or negate it by pressing the change sign key (+ -).
  3. If you are handling a complicated expression just calculate it. When you obtain the final result (a number) use rule 1 or 2 above.

How do you represent the set of rational numbers in symbol form


hi maybe the formula below will help you

A rational number is a number that can be expressed as a fraction with an integer numerator and a non-zero natural number denominator. Fractions are written as two numbers, the numerator and the denominator, with a dividing bar between them. In the fraction written mn or
61f3a73e6711407c72f79e8deb797c6a.png m represents equal parts, where n equal parts of that size make up one whole. Two different fractions may correspond to the same rational number; for example 1⁄2 and 2⁄4 are equal, that is:
38aeb170898abdf282b4ef5400015067.png If the absolute value of m is greater than n, then the absolute value of the fraction is greater than 1. Fractions can be greater than, less than, or equal to 1 and can also be positive, negative, or zero. The set of all rational numbers includes the integers, since every integer can be written as a fraction with denominator 1. For example −7 can be written −7⁄1. The symbol for the rational numbers is Q (for quotient), also written d45a4aa156a8ac07ab80e7d9cf5fa79f.png.

Calculation with angle


Hello,
You perform all calculations in complex mode. When you need to convert to angle amplitude, in the [RUN] screen press [OPTN][F3:CMPLX]
To obtain the angle press [Arg] ( complex number) [EXE]
To obtain the magnitude, amplitude press [Abs] (complex number) [EXE].
Since the [ANS] memory keeps only the last value calculated, you may have to store your result (the complex number) in a variable.

1+ 1 i [white right arrow under tan key to store] [ALPHA] H
Display shows 1+1i. Then
[Abs] [ALPHA] H [EXE] gives 1.414213562
[Arg] [ALPHA] H [EXE] gives 45

Hope it helps.
