HDM-browser for simplified HTM(L) documents (with a ".jav" subset)
XPaint Version 1.85 : tool for drawing
- multiple text-lines and formulas
(automatic determinant calculation for 2*2 and 3*3 matrices that are used in formulas)
- runways and ships can be set as predefined stamp
- sizeable triangles, prisms, (divided) circles, (splitted) 3D cubes and aircrafts

fairly realistic flight-simulation mode for 1 aircraft + optional 1 cube [building] and/or
1 runway as landscape )
chemical draw tool (Version 2.67)
instantly draws userdefined molecules and (cyclic) chains of C,H and CH2 atoms
and alcane, alcanol and alcanoid acid molecules
polynome tool : analytical solution of P2(x) ; verbous numerical solution with automatic mesh-width selection of Pn(x) ;
analytical derivation of f(x)=Pn(x) and computation of f(x)2 , f(x)+g(x) and f(x)*g(x) (up to degree 20 of the solution polynome)
