Mod Arg on Caclulator (1 Viewer)

[dawso]

gday all

i remember a while back someone at school was showing me how u can plug in any imaginary number to ur calculatopr and press keys etc and calculate the mod /arg for that number (good for weird val;ues)

ive got a sharp....does anyone know how 2 do this or hit me up with a useful link?

cheers

I remember seeing an "i" on a calculator once and it looked like a normal casio, except it was way cooler. I think I remember the teacher saying that they are banned...

 

[dawso]

nah they arent banned, i did it on my basic sharp calculator which i used in last year's hsc and is approved, u can do it on all of em, come one, someone show me how 2 do it again.... (it used the x, y underneath the 'STO. button from memory..."

I got a casio fx-100s. There is an i button which is same as the sto-rcl button.

First Change it to Complex mode or "cmplx" mode or something, then to punch in 2+3i:

{ 2 } { + } { 3 } { STO/RCL/i } { = }

Then there is a arg button on my { ( } key, so to find arg:

{ 2 } { + } { 3 } { STO/RCL/i } { = } { SHIFT } { ( / Arg } { = }

similarly for mod, or my { |z| } key

not all calculators have it tho. it aint that much of a bitch to do it yourself

lol so lazy dawso....

oi fuck off dula, its actually really handy.....in the trial, when we had the complex in question 8, the numbers were really shitty and i wanted 2 use it 2 confirm i had the right answer before i hacked into pages of algebra, buit i couldnt remember how 2 do it.....its just handy 2 know

I refuse to use a calculator!! (Unless doing Perms N Combs lol)

{Pol(} {x value} {,} {y value} {)} will give you the mod on a Casio without complex mode. {RCL} {F} (or whatever is used to recall value in F) gives angle.

I so hope that this Q1/Q2 question ends with "Show all working."
