What is a conjugate of an imaginary number?

In mathematics, the complex conjugate of a complex number is the number with an equal real part and an imaginary part equal in magnitude but opposite in sign.

How do you define a variable on a TI-89?

You can save something as a variable by typing the value, followed by the STO button (to the left of the 1 button on the TI-89 and to the left of the spacebar on the Voyage 200) and then typing a variable name.

What do you mean by complex number and complex conjugate?

How to display complex numbers in rectangular form on the TI-89?

Once only, you need to tell the TI-89 that you want results in rectangular mode. [MODE] [▼ 5 times] [►] brings up the choices for complex format. Select [2] for Rectangular and press [ENTER]. For complex numbers in rectangular form, the other mode settings don’t much matter. Polar Display Mode

Can the TI-89 do complex calculations in polar form?

Summary:Your TI-89 can be set up to do all calculations with complex numbers in polar form or rectangular form. Here’s how. (The same keystrokes should work with a TI-92 or Voyage 200.) See also:A separate TI-83/84 procedureis also available.

How do you display results on a TI-89?

Selecting the Display Format You can tell your TI-89 to display results in rectangular or polar form by setting the mode (below). But however you set your calculator to display results, you can always enter expressionsin rectangular form, polar formor a mixture.

What is the angle for the complex number -16+47i?

The angle will be in radians or degrees, according to the calculator mode. Example: What’s the angle for the complex number −16+47i? To begin with, since the number is in quadrant 2 (negative real part, positive imaginary part), the angle must be between 90° and 180° or between about 1.7 and 3.1 radians.
