The following screen shows that functions EXPM and LNP1 do not apply to

complex numbers. However, functions GAMMA, PSI, and Psi accept complex

Function DROITE: equation of a straight line

Function DROITE takes as argument two complex numbers, say, x

, and returns the equation of the straight line, say, y = a+bx, that

contains the points (x

). For example, the line between points

A(5,-3) and B(6,2) can be found as follows (example in Algebraic mode):

Function DROITE is found in the command catalog (‚N).

Using EVAL(ANS(1)) simplifies the result to:
