A SHORTCUT : After putting the upper and lower limits , multiply the minus sign inside the bracket and multiply and divide the whole term by 2j . Then you'll directly get the formula of sin(nwt) which is (e^jnwt - e^-jnwt)/ 2j .
Not sure if this helps clear the steps in 9:50. I apologize in advance if my response has confused you further 😅. Recall that cosine is an even function and sine is an odd function. Now what do we mean by odd and even functions? Simply put it refers to symmetry or in simple terms x(-t) = x(t) for even functions (The function looks the same when reflected over the y-axis). Likewise, x(-t) = -x(t) for odd functions (The function is a mirrored copy reflected over the x-axis). Since cosine is an even function, cos(-x) = cos(x) and similarly since sine is an odd function sin(-x) = -sin(x). This is what the video instructor utilized in 9:50. You can also check the odd and even properties by using values from the unit circle and plugging in for (x). Hope this helps and once again I am sorry if I confused you more 😁
@Erhan Konak I agree we dont need them, but the way they set up the integral they split it into 3 regions. The two zeros and the one that is A0. If you look at the first integral it should not include the tao/2 because that interval is not always zero.
The derivations can be done pretty easier.. more complex methods used to raise standards ig and without symmetry concept, u are trash talking about Cs , Cas here seeming the topik difficult..🙄
Even after 6 years your videos still the best by this intelligent way of teaching. You are an absolute genius
thanks!
This is the best series on Fourier Analysis that I have seen! Thanks for posting them and being so thorough, and taking your time working through it.
You did not remove minus from -1/jnwo, it will change the whole solution.
agreed
sir changed it brother.
see at 10:32
yes
Watch the complete video. He changed it.
I feel batter after see this video thank you 😍😍😍good job
But note in minute 6:55 disappear negative how did that happen,please????
It's simply a mistake
Im from VietNam. Thank you . Your chanel help me more
Please refer me in any company😅
Thank you very much. You are a genius. 👍👍👌👌🙏🙏🔝🔝
Is it always must to calculate the Sampling function too?
integration process is too big... but completely understandable.
thanks sir.
At 6:51 did you didn't you need to carry the negative since it is a constant?
why don't you just leave a comment in video on time 6:51 to clarify it and refer it to time 10:34? I think that is easier for everyone.
Sir what is sint/t why do we need it
What is sampling function?

how about integrate from 0 to t/2 and multiply by 2? i have done this but the answer is not the same ..can u answer sir?
it applies only to even equations
Keep maintain level for gate .
I have seen your all videos. Acc to my syllabus (EE)
Nice one sir
a negave sign is not carried plz view
what happened to minus one at 7:02 where did it go???????????????????????????????????????????????????????????????
At 9:50 Why cos(x) is equal to cos(-x) and same with sin(x) and sin(-x)?

i must thank you guru of teaching but be kind and upload Laplace and Z transform please!
Hello sir at 6:44 you have forgotten a negative sign in calculation of cn
I think there was an error in the first integral (2:57). I believe it should go from -T0/2 to -Tao/2 .
@Erhan Konak I agree we dont need them, but the way they set up the integral they split it into 3 regions. The two zeros and the one that is A0. If you look at the first integral it should not include the tao/2 because that interval is not always zero.
best series
Thanks sir. Your lessons are greatly simplify
WHY DONT YOU PUT To = t , its the time period
Sir if we clamp the signal Fourier coefficient will change or same??
why we found out the ans in terms of sampling function?
Thank you
Good job sir
thank u sir
in the last part of the video, why did you exclude j -imaginary inside of sin(nwt). Wasnt it supposed to carry on?
Nevermind, its Eulers
Can we solve them by normal fourier transform
is it necessary to integrate by changing into theta. TIA.
Not necessary
good series
Complex exponential Fourier series and exponential Fourier series both are same or not
What is the fundmental time period
thanks a lot Sir. Tremendous
Sa function or sinc function
sir how to plot scaled Fourier series coefficients graph plzz tell me about it
Is Tao supposed to equal Pi?
What is sampling function
Do I just multiply the final answer by 2 to get an?
Sir please make videos on z transform.After 4 days its my exam. Please help..
how you get x(t) for a triangular wave
confused with value of x(t) please reply
❤❤❤❤❤
the solution has overextended, it could be solve in 5 minutes
Can any one tell how to plot its spetrum and phase
The reference please😐😐🙂
next semester?
You over complicated that integration.. Simply take that jnwo as constant..
how
Maths is about logic. While this guy is trying his hard to make things look as complicated as possible.
Correct ✅
The derivations can be done pretty easier.. more complex methods used to raise standards ig and without symmetry concept, u are trash talking about Cs , Cas here seeming the topik difficult..🙄
