Note: When using trigonometric functions and their inverses with complex numbers the arguments are no longer angles. Therefore, the angular measure selected for the calculator has no bearing in the calculation of these functions with complex arguments.
Function DROITE: equation of a straight line
Function DROITE takes as argument two complex numbers, say, x1+iy1 and x2+iy2, and returns the equation of the straight line, say, y = a+bx, that contains the points (x1,y1) and (x2,y2). For example, the line between points
