We have converted a complex number from polar form (using degrees) into rectangular form. Of course, you have to be careful that you have your calculator set correctly in degrees (or radians, if required). Example 2 Convert 12−42j12−42j to polar form (r∠θr∠θ). For CASIO calc...

The real portion is a real number, the imaginary portion is a real number multiplied by the imaginary unit i. For example, you can enter a number such as 3+2i. A complex number in Polar Form must be entered, in Alcula’s scientific calculator, using the cis operator. To enter the ...
1. When finding the angle for the polar form, what do you have to do to your calculator's answer to find the correct answer if the complex number is in the fourth quadrant? Leave it alone. Add 90 degrees. Add 180 degrees. Add 210 degrees. Add 360 degrees. 2. Which of the followin...

To obtain the reciprocal, or “invert” (1/x), a complex number, simply divide the number (in polar form) into a scalar value of 1, which is nothing more than a complex number with no imaginary component (angle = 0): These are the basic operations you will need to know in order ...
Euler's Formula is also known as theexponential formof a complex number because it creates the connection between trigonometric and complex exponential forms.

An alternative,polarnotation, expresses a complex number as (r e^it) where e is the base of natural logarithms, and r and t are real numbers, known as the magnitude and phase. The two forms are related: r e^it = r cos(t) + i r sin(t) = x + i y where x = r cos(t) ...
