A short history of complex numbers orlando merino university of rhode island application of algebra to geometry from which we now have cartesian geometry. a so-called complex number, z = x + iy, has both, a real part (re(z) = x) and an imaginary part (im(z) = y). the complex conjugate z* of z one obtains by flipping the sign of all terms with an i in them, i.e., z* = x œ iy. leonhard euler (1707 œ 1783) discovered the relation, which relates complex numbers to

The intent of this research project is to explore de moivre’s theorem, the complex numbers, application of this theorem, nth roots, and roots of unity, product of complex numbers. the english geometer w. clifford (1845–1879) devel-oped the “double” complex numbers by requiring that i2 = 1. clifford’s application of double numbers to mechanics has been supplemented by applications to noneuclidean geometries. the german geometer e. study (1862–1930) added still another variant
