HELMHOLTZ
COIL ANALYSIS Calculated magnetic field B as functions
of distances x along

axis and h away from it.Gnu
Octave code for HELMHOLTZ
HERE (probably OK for
Matlab
as well), but note that the integration function trapz(x,y) may need
to be replaced by
cumtrapz(x,y)
in the latest versions of Octave (and perhaps Matlab as well).

FOR AN ELLIPSE
a proof that if the distances of a point from x = --a and x = +a add
up to a constant
then the point traces out an ellipse

INTEGRAL SOLVER- Enter "integrate" followed
by the algebraic expression, or select
the orange icon on
the right. These will both give an algebraic answer.
