Ano exactly ang di mo maintindihan sa fourier series?

Purely substitution ang fourier series, another practice factoring and wag mo kalimutan basics ng trigo, say cos90, sin45, etc...

Sa mga cancellation and simplification kaya biglang may mga naglalaho sa fourier series, another, meron pa yang odd and even series.

example: given the periodic function f(t) determine the trigonometric fourier series expansion of f(t) using direct evaluation of trigonometric coefficients

pahelp po pano po toh

Yung Elementary Differential Equations Book ni Rainville meron duun sa bandang last part ng book kaso hirap nmn intindihin  ???  ???

Pero kung gus2 mo mas madaling intindihin yung mga book ng Advance Engineering Mathematics basta yung author ay yung mga foreign prof wag kang magrerefer sa local authors kasi kulang yung mga yun at saka di masyado detalyado basta n lng nilagyan ng mga topic n di nmn masyado revelevant At saka masyadong short cut...  ??? ???

Rainville has some challenging problems, kaya lang di detailed ang mga explanations nya sa Fourier Series, Kreyzig naman, mga shortcuts, I would suggest go for Wiley and Barret na book.

@ zhi_hong
just ko give you an idea kung anong ginagawa ng fourier series..
i made a sample sheet sa MathCAD13..
note: HINDI pa ito ang sagot..

sa Mathlab, halos wala akong kaalam-alam..  :'(
ito kasing MathCAD, ginagamit din namin sa work, kaya napa-familiarize ako.. hehe  ;D

off-topic:

parameters ng magnetics, circuits?

hindi gaanong helpful yung MATLAB pagdating sa ganun...sa MathCAD kasi pwede yung iterations...ako OpenOffice Spreadsheet na lang gamit ko... ;D hindi lang kaya yung mga mathematical functions...pero meron din atang math suite ang openoffice...

na hi-jack na natin itong thread na ito.. hehe  ;D

yup, ginagamit din sya sa magnetics... very useful yung built-in units and constants sa MathCAD..
may gumagamit din samin ng Mathlab, pero mas preferred ko ang MathCAD kasi user-friendly and wala kang makikitang weird syntax.. hehe  ;D
