POLAR form of a Complex Number.

[@DComplexAnalyzer]

Great video... Based on your explanation, you calculated the value of theta, i.e, the argument using arctan(b/a) and u didn't neglect the sign of a and b (whether negative or positive) and u always change the resulting angle (if negative )to positive by adding 360⁰ to it..... .... But some others authors and videos neglected any negative sign of a and b.... Like for example, -2+3i,...... You did something like arctan (3/-2).... But some others will just remove the minus and say arctan(3/2)..... CAN U PLS EXPLAIN THIS concept sir😊

Good work❤

Please is it always necessary to put the pie..?

[@travoltavatileni7494]

Can sir do an example in the 3rd quadrant

[@MakuachAchiek-rt3qx]

Thank you so much sir

[@nishnaomiingado6594]

Wow

[@aliyudalhatu8823]

Please how can we calculate the value of the tan inverse in π?

[@risingrookie7]

You will divide the number by 180…let’s say you get 30 you will divide it by 180 which will give you 6,then you put it under pi. So 30 degrees will become pi/6

Thanks sir 🙏 this helped a lot!

Sir for Z = -2√3 + 2i the polar form is Z = 4(cos5Π/6 + isin5Π/6) and not Z = 4(cos11Π/6 + isin11Π/6)

[@tambuwalmathsclass]

Why?

[@kelechifidelis6411]

@@tambuwalmathsclass if we solve back Z = 4(cos11Π/6 + isin11Π/6) we won't get Z = -2√3 + 2i

[@tambuwalmathsclass]

You are right

[@kelechifidelis6411]

@@tambuwalmathsclass correct answer is Z = 4(cos5Π/6 + isin5Π/6)

Sir 4th quiz is it πover 2 or over 4

[@gift4183]

How do you convert tan inverse to pi?

Please how did you get the pie

[@miguelntap8406]

Sir the last one is wrong because π-π\6 = 5π\6

[@Stephenie-mn1dz]

Sir for numbers that the tan inverse has decimals how can you express them in terms of Π

[@julianaesuon]

change the settings of your calculator from 'comp' to 'rad' before calculating the tan inverse

[@Stephenie-mn1dz]

Sir i still don't understand how you get the Π

*π (This is a joke ok pls don't take it too seriously)

If a question is 7i- (4+5i)

[@barney2.1]

Rewrite it as -4+3i
