WebMar 27, 2024 · The trigonometric polar form can be abbreviated by factoring out the r and noting the first letters: r(cosθ + i ⋅ sinθ) → r ⋅ cisθ. The abbreviation r ⋅ cis θ is read as “ r kiss theta.”. It allows you to represent a point as a radius and an angle. Take the following complex number in rectangular form. 1 − √3i. WebJan 3, 2012 · Snell's Law states that n 0 sin ( θ 0) = n 1 sin ( θ 1) . For absorbing materials (or conductive like Au or Ag) the " n 1 " is a complex number. This requires that θ 1 also be complex. Many areas in physics use what's called the Euler formula, which relates trigonometric functions to complex exponentials.
