The following screen shows that functions EXPM and LNP1 do not apply to
complex numbers. However, functions GAMMA, PSI, and Psi accept complex
numbers:
Function DROITE: equation of a straight line
Function DROITE takes as argument two complex numbers, say, x
+iy
and
1
1
x
+iy
, and returns the equation of the straight line, say, y = a+bx, that

contains the points (x
,y
) and (x

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:
