Hello, atm I have this solution:

optn->angl->pol()

222+333i -> pol(222,333) = answer + degrees

angl->rec()

10ohm 45degrees -> rec(10,45) = answer + i number

Hope this helps.

For algebra fx 2 writing complex numbers in polar form is so easy ... remember x+jy = r*e(j*theta) for example if we have r=5 , theta = 10 degree write ---> 5e(10*pi*j/180) multiply by (pi/180) to convert from degree to radian

If one or both numbers are in polar form, convert it/them to rectangular. Once both numbers are in rectangular form, simply add the two components separately: Add the two x components together, and add the two y components together.

If you're asking how to do this on a particular calculator, please specify the make and model.

At first, **Rect** and **Polar** are a display-format instructions, not a conversion functions. Polar instruction displays complex value in rectangular form **a + bi**. The complex value can have any complex form. __However, an__** r*exp(i*theta)** causes an eror in Degree angle mode according to the TI avowal. See captured images below

Set the calculator to polar form, then simply enter the radius, press the comma key, then enter the angle (in whatever angular mode you've specified).

Full details are in Chapter 2 of the manual you can download from here.

Press Shift, then press + key, input x coordinate, then press Shift and ) key and finally enter y coordinate and press =. You should now get solution (in solution r is radius and theta is angle).

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.

There isn't one. If you're entering a complex number in rectangular form, separate the real and imaginary parts with a comma (left of the 4). If you're entering a complex number in polar form, separate the magnitude and the angle with the angle symbol (2nd comma).

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

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.
