Chapter 1 复数(Complex Numbers) 1.二项式公式(Binomial Formula) 若z1和z2是两个不为零的复数,则 (z1+z2)n=∑k=0n(nk)z1kz2n−k(n=1,2,⋅⋅⋅)其中 (nk)=n!k!(n−k)!(k=0,1,2,⋅⋅⋅,n)3.三角不等式(Triangle Inequality) 三角不等式为我们提供了两个复数的和的模长的...
CLOSURE PROPERTY: An operation is said to be closed on a set of complex numbers if the result of this operation belongs to the set ofwhole numbers. Ifz1andz2are two complex numbers, thenz1+z2,z1-z2,z1z2and$\frac{z_1}{z_2}$ (z2≠0)are complex numbers too. COMMUTATIVE PROPERTY...
Complex Numbers IIIn this lecture, we shall first show that complex numbers can be viewed as two-dimensional vectors, which leads to the triangle inequality. Next, we shall express complex numbers in polar form, which helps in reducing the computation in tedious expressions....

The second question involves using complex numbers and the triangle inequality to solve a problem. Multiple suggestions and approaches are discussed, including using a coordinate system and choosing the origin strategically. The conversation ends with the suggestion to use the tree as the origin for ...
The relationship is in fact expressed in terms of triangle inequality: Squared magnitude can be expressed as a product of the complex number itself multiplied by its conjugate: This can be interpreted in both rectangular (Cartesian) coordinates and polar coordinates: Most of the slick tricks in ...
To solve inequalities involving complex numbers, you can follow the same rules as solving inequalities with real numbers. You can perform the same operations on both sides of the inequality, and the solution will be the same as long as the operations are performed in the same direction....
