Question

Sketch fourier graph > f(t) = t if -pi < t < pi where f(pi + 2pi) = f(t)

Answer 1

- I'm thinking it's just this?

Answer 2

(Through the origin) from -pi to +pi?

Answer 3

This is partly right, but it doesn't fully convey what f(t) looks like. It's indistinguishable from just the graph \(g(t)=t\) right now. To make it clearer make sure you incorporate the periodic nature of the function, \(f(t)=f(t+2 \pi)\) in there.

Answer 4

Slightly confused, it would just be a repeated 45 degree discontinuous line across ?

Answer 5

Yeah, it's gonna be discontinuous, probably not used to that yet but it's not so bad as long as it's periodic for Fourier series.

Answer 6

?
