HI all,
I want to write in sage a 2pi
periodic even function defined by f(t) = -t + pi
, for t
in [0, pi)
. I already checked Defining a periodic function and defining periodic functions on this plateform, but none of the provided solutions works for me. My main issue is that I need a way to transform any real number x
into its unique representative in the interval [-pi, pi)
. For that I used frac
and %
but they both raise errors. Could anyone help me out?
Thanks.
