[Scilab-users] ode with algebraic constraint

[Jens Simon Strom]

Hallo Rafael,
This mail arrived properly!

To my taste  the equation of motion of a spherical pendulum (which we 
are actually treating here) is much easier to understand in the way you 
presented it than the one in spherical coordinates filling the 
textbooks.  Perhaps Lagrange and Hamilton are so fascinating that 
outhors miss the simple route and prefer to play with advanced methods.

I prefer not to use a numerical controlled milling machine when a simple 
fad can do it too.

Best regards
Jens
