This complex exponential function is sometimes denoted cis x ("cosine plus i sine"). The formula is still valid if x is a complex number, and so some authors refer to the more general complex version as Euler's formula.

WebMay 5, 2011 · I have a concern about the notation Mathcad uses for simple trig functions. I've had this concern for years, but it has come to the forefront again with the use of Prime, which (thankfully!) tries harder to make the equations look typeset.
