At 13:13 by mistake i wrote that sum of Fourier series at x=0 is (1+1)/2=1. There is a mistake, here left hand limit is -1 and right hand limit 1 so Average will be 0.

At discontinuity the mid point of the Fourier function at the point of discontinuity is the sum of Fourier series at a discontinuity.

Great video sir💥💥. Can you take some more problems on half range concept??

@DrMathaholic 4 жыл бұрын

Okay. I will make a video on half range in a day or two.

Made one video on half range.. hope this will help you. Here is the link- kzfaq.info/get/bejne/pdOfaJSIqtvVm3k.html

At x=0, in sine series how we get that please explain it.

Sir at 6:00 no need to find bn na as f(x) is even function ?

@DrMathaholic 2 жыл бұрын

See the graph for the function. Is it even?😀 We have defined from 0 to 1 and not -1 to 1.

see graph which i drew before writing coefficients.

Sir at 3:25 LHL is 0 and RHL is 1 at x=0 so avg must be 1/2 right...i mean should we check the values from graph or should we do it using formula?

@DrMathaholic 2 жыл бұрын

Yes you are right..average is 1/2.. thanks for pointing it out..you can approach by whichever way is easier for you

sir at 5:39 why is the limit of integration 0 to 1 and not -L to L

@DrMathaholic Жыл бұрын

Here the function is not defined from -1 to 1. It is defined over 0 to 1 and we have to fourier series of given function over 0

Sir will it be mentioned in the ques that we have to solve it by half range expansion?

@DrMathaholic Жыл бұрын

Yes...technically they should... If not, then other way of asking this is - find cosine series for the given function... Or Find sine series for the given function.. Then they will also fall under the category of half range..
