Motivation for each concept is exceptional, keep up the good work!

Hello ! You Said that the set U ( set of all cos( k * x ) , sin( k *x) ) is linearly independant and that s not hard to show buuuut it’s seem kinda hard for me ^^ we need to show that if the linear combination of all elements is 0 that implies that all coefficient are 0. I tried evaluating the linear combination at different point but we have series here and infinately many coefficient ^^. Can you give me a hint pls ? :) Ty for reading and GREAT VIDEOS !!

Thanks! My Abstract Linear Algebra series does that. Check it out :)
