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 name for this function in software libraries. WebAug 15, 2024 · Another way to tell the isomers apart is the bond angles: cis isomers have a 90 o bond angle whereas trans isomers have a 180 o bond angle. Mer-Fac Isomers.
