Webcis(x) cos(x) + isin(x) cis(x) Not everybody is familiar with the "cis" notation. If you use it, define it first, so they know you mean what is shown in the first line. ∠ A: angle A cis is a mathematical notation defined by cis x = cos x + i sin x, where cos is the cosine function, i is the imaginary unit and sin is the sine function. The notation is less commonly used in mathematics than Euler's formula, e , which offers an even shorter notation for cos x + i sin x, but cis(x) is widely used as a … See more The cis notation is a shorthand for the combination of functions on the right-hand side of Euler's formula: $${\displaystyle e^{ix}=\cos x+i\sin x,}$$ where i = −1.
