Algebraic concepts and their expression in language A study of pupils between 13 and 16 yearsH.N Sakonidis
The imaginary part starts with 0 (zero) in cell C25 and is increased by (1/2)π or 45 degrees for each cell below. The real number is always 0 (zero) in this example. The IMEXP function calculates the exponential in cells D25 and below for each complex number and the result shows...
