ATTN: @RRITESH KAKKAR

Don't worry too much about @Aleph(0) 's 2'nd and 3'rd exercises -- they are not properly framed questions - That is to say, as presented, they're merely 'thought exercises'

That said I agree that you should try to answer her first exercise:

1 If complex number is written in rectangular form like 32+12i which you can think of like 32+(-144)^.5
What are the angle and magnitude when you think about it as vector?

Best regards

32+(-144)^.5???
ok .5 mean √

 

32+12i

magnitude = √32²+12²=34.17
angle= tanφ=12/32=0.375
φ=20.55°

 

then how were you earning?

Ya know... If you'd concern yourself with your studies instead of everyone's personal business you be on to your doctoral work by now!

Seriously, unsolicited personal questions are generally perceived as rude ('round here anyway)

 

then how were you earning?

By working as an IC design engineer.

magnitude = √32²+12²=34.17

Very Good! --- See what comes of a bit of effort?

 

By working as an IC design engineer.

integrated circuit or internal combustion engine

Given the nature of this forum, what do you think the most reasonable interpretation is?

 

ok, it ic circuit.

you must be using wafer

 

Given the nature of this forum, what do you think the most reasonable interpretation is?

Interdimensional Channeler?

 

@RRITESH KAKKAR

I need to know - are you serious about learning mathematics or is it merely a topic of discussion for you...

ok let work.

I can be of more help to you if you tell me where your (mathematical) 'strengths and weakness' lay -- For instance you seem to have trouble formulating equations (as from verbal exercises) as well as with apprehension/manipulation of inequalities -- while, on the other hand, you seem quite proficient at manipulation of 2'nd degree equations and application of vectors...

Sincerely

yes.

 

How to add this source?

how to solve this?

 

yes.

It's not a yes or no question -- I need to know in what areas of math you require exercise/training

 

which will increase my capability and remove lazy

Not if you keep asking "How to solve this problem"
