Question

what is the period for the fourier expansion of
f(t) = { 5, 0<= t <= 2; 0, 2 14 years ago

Answer 1

because normally the question i'd encountered has the same interval, eg -2<t<0; 0<t<2 etc.

Answer 2

maybe we can do a shift of the function by substituting u=t-2

Answer 3

this can be transformed into regular Heaviside function
