Complex numbers and trigonometry
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. Web2 days ago · Finding the Cosine of Complex Number in Golang - The cosine function is a trigonometric function that is used to determine the ratio of the adjacent and hypotenuse sides of a right triangle.
