Half range Fourier cosine series of sinx in (0, π) || 18mat31 || Dr Prashant Patil

[@joysbta3072]

In an value there should be minus in front of (-1)^n

Thank you sir, I cleared m-series subjects with help of your lecturing vidios😍

[@royalkingpuratchipadai9384]

Think you sir your teaching is easy to understand sir 👍💯

Find fourier series of f(x) =sinπx in the interval 0

[@aware-z4j]

You said minus2 by n-square minus 1 but you didn't put minus sign infront of 2... But you got the ans

[@imaniimane1292]

In 04:00 I think 2sin(a)*cos(b)=sin(a+b)+sin(a-b) it's not the one you used in which there is - instead of +

Thank you so much sir 👍👍👍

Thank you soo❤️ much sir I really loved it❤️

[@khadijahnoushad7675]

Sir at 8.08 it is -2/n square-1π Does this change the answer please tell

[@j...125]

Yes

[@dhavalbaraiya3177]

Thanks sir❤️

[@great-aryan]

Yeh open range 0 to pi (0,pi) Or closed range [0 to pi]

Good Video

Nic video ❤️

As we can comment on even or odd of any function onnly in the interval (-L,L) not on (0,L) ...then how we can write cosine series

[@yashi_13]

Sir this half range so where is bn?

[@fq20fartalesuraj26]

Value of an is in minus

[@anushkajaiswal8515]

But sinx is neither odd nor even in the given interval .then how can we apply cosine series formula

[@DrPrashantPatil7899]

As We r calculating for half range We r extending sinx as even function in -pi to pi

[@anuk4430]

Sinx is an odd function isn't it ?

[@naeefdalvi5725]

At 9:30 , integration of sin 2x will be -cos2x/2..

[@DrPrashantPatil7899]

Thank you for your keen observation, and that is not going to change the final answer.

[@funny-p2556]

At 8:08, this is -2/nsquar-1

[@khadijahnoushad7675]

@@funny-p2556 Does this change the answer

[@sonisebastiant9217]

In the 1st term u r saying minus 2 divided n square minus 1, but it is written only +2 by n square minus 1, and u r proceedings with +2, so please verify.

[@jayanand8957]

Tq so much sir
