## Polar Form of complex numbers-

In the previous post, we discussed the basics of complex numbers.This is the second and final post on the complex numbers.here we shall discuss, polar form of complex numbers
We consider complex numbers like vectors and every vector must have some magnitude and a certain direction. If we write a complex number in form of a point in the Cartesian plane/ordered a pair like x+iy=(x,y) then the distance of this point from the origin (0,0) is equal to the magnitude of our complex number while the angle it’s making with x-axis will show it’s direction.

## How to Get 7 in Ib Maths hl

Many of my students got “7” in their IB Maths HL paper people so I believe my suggestion would be useful regarding this-

I think that students should solve their problems in one go. I don’t believe in following some “10 minute before your sleep” tips. All your hard work will go in vain if you forget chapter 3 while doing chapter 4 and because many times the hard questions a require knowledge across many chapters. What you need is a period of intense and thorough revision, in which your free study time is totally devoted to Math HL.

In the process of revision, Students should study the sections one after another.Textbooks split chapters into different sections with practice questions given at the end of each section.If you do not have such a textbook, please buy a good and I think there should be NO “I don’t know how to buy” issue).

### Students should follow these instructions-

Instruction 1. Read the whole body of the section carefully.Students should understand it in the best possible way

Instruction 2.Try the practice questions in the order of their difficulty level.you should not waste time on questions which you know, are very easy for you.Make a list of the questions you can’t do.Once the number of the listed questions reached 25-30% of the whole practice set, you should stop solving the questions and go back and study the body text because there is surely some concept that you are still missing.Once you are done with your reading, you can try your listed questions again.If the problem persists, you need expert help.you should go to your teacher or seek online help at ib elite tutor.
