Test each of the following series for convergence.

∑(1+i1-i3)n

Short Answer

Expert verified

The series is convergent.

Step by step solution

01

Given Information

The series is ∑1+i1-i3n.

02

Definition of the Convergent series.

A series is said to be convergent if the terms of a series get close to zero when the number of terms moves towards infinity.

03

Test the convergence.

The series is ∑1+i1-i3n..

An=∑1+i1-i3nAn+1=∑1+i1-i3n+1

Find the limit limn→∞An+1An.

p=limn→∞An+1An=limn→∞1+i1-i3n+1×1-i31+in=limn→∞1+i1-i3

p < 1, Hence the series is convergent.

Solve for all possible values of the real numbers xand yin the following equations.

x+iy=0

Express the following complex numbers in the x+iyform. Try to visualize each complex number, using sketches as in the examples if necessary. The first twelve problems you should be able to do in your head (and maybe some of the others—try it!) Doing a problem quickly in your head saves time over using a computer. Remember that the point in doing problems like this is to gain skill in manipulating complex expressions, so a good study method is to do the problems by hand and use a computer to check your answers.
