Is z1 z2 z3 are vertices of an equilateral triangle?

The complex numbers z1, z2, and z3 satisfying (z1-z3)/(z2-z3) = (1-i root 3)/2 are the vertices of a triangle which is (1) Equilateral (2) Of area zero (3) Right-angled isosceles (4) Obtuse angle isosceles. So the triangle is equilateral. Hence option (1) is the answer.

What is the value of z1 z2 +z3 if z1 z2 and z3 are complex numbers such that z1 1 z2 1?

If z1, z2 and z3 are complex numbers such that |z1| = |z2| = |z3| = |(1/z1)+(1/z2)+(1/z3)| = 1 then |z1+z2+z3| equal (1) equals 1 (2) less than 1 (3) greater than 1 (4) equals 3. Hence option (1) is the answer.

What is z1 z2?

z1 + z2 = (a1 + a2)+(b1 + b2)j. z1 − z2 = (a1 − a2)+(b1 − b2)j. So, to add the complex numbers we simply add the real parts together and add the imaginary parts together.

What does z3 mean math?

The unique group of Order 3. It is both Abelian and Cyclic. Examples include the Point Groups and and the integers under addition modulo 3. The elements of the group satisfy.

What is the formula of z1 z2?

z1/z2 = (x1+y1i)/(x2+y2i) is a complex number, provided that z2 = x2+ y2i 0. x22+ y22 0. To get the equation (1.12), we force the complex denominator to be real by multiplying both numerator and denominator by the number x2 -y2i.

How do you prove z1 z2 <= z1 z2?

(y1x2 – x1y2)2. It is true because x1, x2, y1, y2 are all real. = |z1||z2|….Properties of the modulus of the complex numbers.

Triangle Inequality:	Proof
1. |z1 + z2| |z1| + |z2|	Proof
2. |z1 + z2| |z1| – |z2|	Proof
3. |z1 – z2| |z1| – |z2|	Proof

What is Z3 symmetry?

The alternating group on three elements. The group of orientation-preserving symmetries (rotational symmetries) of the equilateral triangle. The multiplicative group of the field of four elements. In particular, it is the general linear group .

What is z1 and z2?

z1 + z2 = (a1 + a2)+(b1 + b2)j. z1 − z2 = (a1 − a2)+(b1 − b2)j. So, to add the complex numbers we simply add the real parts together and add the imaginary parts together. Example If z1 =13+5j and z2 = 8 − 2j find a) z1 + z2, b) z2 − z1.

What is the sum of complex numbers z1 and z2?

By definition of addition of complex numbers (1.10) z1 + z2 = (x1 + x2) + i(y1 + y2).

How do I prove if z1 z2 z1 z2 then find the range of arg z1 z2 )?

First, the ordering of terms within the set is unimportant.

Is z1 z2 |=| z1 z2?

Therefore, |z1+z2|2=|z1-z2|
