In this lesson we learn how to use exact values to convert complex numbers from Polar form to standard form, so we don’t have to write them with rounded decimal numbers.
In this lesson you learn how to convert a complex number from polar form to standard form. In fact, we show you how to convert from standard to polar then back to standard again.
In this lesson we explain how to convert a complex number from standard form to polar form. We show you the theory behind it all first and then we explain how to do it quickly.
This lesson we talk about how the argument has to be between -180 to 180 degrees, so if the complex number has a negative imaginary part then it will have a negative argument.
In this lesson we talk about how to find the argument of z – the angle between the line segment joining the origin to z and the positive x axis.
In this lesson we talk about how to find the modulus of a complex number.
In this lesson you will do a quiz that requires you to find the value of unknown variables using the concept that the real part of the left hand side equals the real part of the right hand side, and that the imaginary part of the left hand side equals the imaginary part of the …
In this first complex numbers quiz we do a question on using the Re() and Im() functions.
In this lesson we learn how to multiply two complex numbers together by doing binomial expansion, and we also look at the effect of doing this geometrically.
In this lesson we talk about how to multiply a complex number by a scalar quantity and how to represent this on an Argand diagram.
