Webb14 mars 2024 · This is why, in the trigonometric notation of the complex numbers, we write e i t = c o s ( t) + i sin ( t): the real numbers cos ( t) and sin ( t) are, respectively, the real and imaginary parts of the complex number e i t, which is none other than e x p ( i t). 3. Geometric interpretation: Thales and Pythagoras. 3.1. Early study of triangles can be traced to the 2nd millennium BC, in Egyptian mathematics (Rhind Mathematical Papyrus) and Babylonian mathematics. Trigonometry was also prevalent in Kushite mathematics.
