WebYear 12 Topics. Multiplying and Dividing in Polar Form. Multipling and dividing complex numbers in rectangular form was covered in topic 36. In polar form, the multiplying and dividing of complex numbers is made easier once the formulae have been developed. The following development uses trig.formulae you will meet in Topic 43. WebComplex numbers in the angle notation or phasor (polar coordinates r, θ) may you write as rLθ where r is magnitude/amplitude/radius, and θ is the angle (phase) in degrees, for example, 5L65 which is the same as 5*cis(65°). Example of multiplication of two imaginary numbers in the angle/polar/phasor notation: 10L45 * 3L90. For use in education (for …
