I got problems in two topics.
First one is with solving equations and inequalities having modulus in them.
For example |x – a| < b ⇔ a – b < x < a + b
So what are the solutions of other equations and inequalities?
|x – a| > b
|x – a| > |b|
|x – a| > |b - c|
|x – a|^2 > b^2
|x – a|^2 > |b|^2
(x – a)^2 > b^2
And anything I missed.
Also I got problems with argand diagrams.
How do you draw stuffs like |z – a|< k, |z – a|= |z – b|, arg(z – a) = α.
Also it would be awesome if you could help me draw some other of the notations of complex numbers.
