The title may sound a little bit odd, but I was wondering if anything has ever been documented about functions that aren't periodic in the sense , but rather (if {p} represents an operator of p magnitude and }p{ reps its root inverse)

I ask because I've come across a curious set of "lowered operator" trigonometric function; if 0 <= q < 1, ;

or is the identity function,:

they satisfy

they follow all the laws sin and cos follow only with lowered operators (using logarithmic semi operators); ie

Pretty much any trigonometric identity you can think of these lowered operator trigonometric functions obey.

They also have a logarithmic semi operator Taylor series very much the same as their sine and cosine counterparts.

if

then

it can also be shown that if
