Polar rectangular


There is nothing to convert, because if T is a real number so is 40sin(4000T).
40sin(4000T)=40abs(sin(4000T))*sign(sin(4000T))
where abs() is the absolute value of it argument, and sign(sin(4000T)) is positive or negative.
So in (radius, angle) polar coordinates
r= 40 abs(sin(4000T)),
theta =(0, or PI), depending on sign(sin(4000T))

If you are trying to graph parametric functions, this calculator does not do graphs, and you need another function of T

How do I convert between the rectangular and polar form of a number with imaginary values? i.e. I want to take the number a+bi and convert it to polar D<(angle) and vice versa.


Use the >Rec and >Pol commands. They're in the Complex number menu, accessible through 2nd [CPLX] MORE.

[CPLX] is the shifted function of the 9 key.

Converting between Forms When working with phasors it is often necessary to convert between rectangular and polar form. To convert from rectangular form to polar form: M = sqrt{A^2 + B^2} f =...


You can switch the display mode for complex numbers by pressing SHIFT MODE down 3 and picking one. This will display the current result in the selected mode.

You can also override the current display mode and specify the format. Add these keystrokes at the end of a calculation: SHIFT 2 then 3 for polar or 4 for rectangular.

Can you show how to convert pola to rectangular o


Hello,
To avoid errors make sure that the angle unit is THE ONE required by your problem. To verify or to change the angle unit press [SIFT][MODE] and select [3: Deg] for degrees, [4:Rad] for radians, or [5:Grad] for grads.

Convert from rectangular to polar

[SHIFT][+] (Pol) . Screen displays Pol(
You enter the X-coordinate, and the Y coordinate separated by a comma, then you close the parenthesis and press [=].

Exemple: Polar coordinate of the point (1,1)
Pol( 1, 1) gives
r=1.414213562 (square root of 2)
θ=45

Here is how you enter it
Press [SHIFT][MODE][2:LineIO]
[SHIFT][POL] 1 [SHIF] [,] 1 [)] [=]

The screen displays
Pol(1,1)
r= 1.414213562
θ= 45


Convert from polar to rectangular coordinates

Rec ( radius, angle) =

Exemple: Recatngular coordinates of (r=3, θ=60°)
[SHIFT][Rec] 3 [SHIFT][,] 60 [ ) ] [=]
The screen displays
Rec(3,60)
X= 1.5
Y= 2.598076211


Hope it helps.

How to convert polar to rectangular form


Hello,
Press [MODE] and select [1:COMP]
Press [SHIFT][MODE] and select [3:Deg]. You can also use rad if the angle you are given is in radians.
To start the conversion
Press [SHIFT][-] (Rec) screen displays Rec(
Key in the radius r , ex: 3 screen displays Rec(3
Press [SHIFT][)] (,) to enter comma separator Rec(3,
Key in the angle in degrees, ex: 57.3; screen displays Rec(3,57.3
Press ) to close parentheses; screen displays Rec(3, 57.3)
Press [=]
Screen displays
Rec(3, 57.3)
X=1.620720961
Y=2.524532346

X and Y are the values of the coordinates.

If angle is in radians, [SHIFT] [MODE][4:Rad] the command
Rec(3, Pi) gives X=-3, Y=0
Hope it helps

Polar/rectangular


For a TI-86


Converting rectangular to polar
Press "2ND" and then "MORE" for the MODE screen
Highlight PolarC and press "ENTER"
Quit that screen.
Now ready to go.
A example of converting 5+j6
Enter "(5,6)" in the calculator and press "ENTER"
Should get (7.81024967591*angle*50.1944289077)


Converting polar to rectangular
Press "2ND" and then "MORE" for the MODE screen
Highlight RectC and press "ENTER"
Quit that screen.
Now ready to go.
A example of converting 5*angle*35
Enter "(5*angle*35)
Should get (4.09576022145,2.86788218176)


Note
*angle* is the symbol when you press "2ND" then ","


Note 2
To round the an decimal places press "2ND" then "MORE" for the MODE screen and on the line that says float, choose a number on that line for the number of decimal places you would like to have.
