$P(t) = ln|10cos(\pi\frac{t}{n})|$
$t = 0,1, . . .n$
$n \in \mathbb{N}$
I took $n$ as the number of the iteration we're currently on and then $t$ would essentially be $n-1$
Which then left me with:
$P(0) = ln|10cos(\pi\frac{0}{1})| = 2.303$
$P(1) = ln|10cos(\pi\frac{1}{2})| = UND$
$P(2) = ln|10cos(\pi\frac{2}{3})| = 1.609$
$P(3) = ln|10cos(\pi\frac{3}{4})| = 1.956$
$P(4) = ln|10cos(\pi\frac{4}{5})| = 2.091$
Am I on the right track or have I completely missed the mark?
