k = q + 3i and z = k2 - 8k* - 18q2 i. Plug k into w to give: z = (q + 3i)2- 8*(q - 3i) - 18q2 i. k means the compliment of k which just means that the ...
Using an argand diagram we can see that this (in fact all) complex numbers create a right angled triangle and using this fact we can find the modulus of this number. The modulus of this number is the 'r' ...
We must prove the four axioms of a group are satisfied (i.e Identity, Associativity, Closure, and Invertibility). Identity: The identity element is an element e in G such that eRTAnswered by Ross T. • Further Mathematics tutor17535 Views
