• Curve is flipped over the x-axis. • Period is 2π/b = 2π/2π = 1. Perioder[redigera | redigera wikitext].
The case p = 17 is a root of an 8th deg eqn, but can be also given as a sequence of nested radicals, 4cos(2π / 17) = 1 x + √x(17 + 4√17)1 / 4 = 3.72988… x = 1 2(y + √y2 + 4) y = 1 2(1 − √17)

The consequence for the curve representative of the cosine function is that it admits the axis of the ordinates as axis of symmetry.
