Paige: I keep forgetting...what's the cosine of 60 degrees? Jason: Well, let's see...if I recall correctly...1 - (numbers)... Paige: In case you've forgotten, I'm not paying you by the hour. Jason: 1/2.
Good choice Paige.
That infinite series is correct, by the way.
That’s the incorrect cosine value of 60 degrees
Is that Fourier’s series?
