Complex Numbers in Polar Form

I explain the relationhip between complex numbers in rectangular form and polar form. I also do an example of converting back and forth between the two forms.
At time 9:57 I should say...Converting from Polar to Rectangular is very simple. Converting from Rectangular to Polar requires you to think about the final theta measure.

Thank you sir Rob.. The thing that I won't be able to learn the whole semester you made me learn plus saved in my mind in 12.35 minutes video. Tomorrow afternoon is my calculus exam and tonight I'm watching you.. 😂. But Thank you so much sir. You earned a subscriber..

I needed this for precalc. Thank you sir Rob for the calligraphy and the math.

[vijayalakshmiramakrishnan]

Sir I have a doubt. How did you get the value .98?

[elsielin]

i'm confused that how you calculate tan^-1(-3/2)? because my result is -56.3 approximately using my calculator.

Your handwriting is GORGEOUS oh my gosh (Also thank u for the helpful vid)

[Rantofthings.]

Certain topics you learn in math are not going to be clear why you are learning them until you get much farther through math.

Yes, I'm sure it is a real notation if it is in your book...but I am not familiar with that one.

If the point is in quadrant 2 do 180 - reference angle, quadrant 3 do 180 + reference angle:) Thanks for watching!
