Hi Steve,
[As far as I can tell, your post has no issues. Take a look and see
if you see anything wrong. -- Steve C. Moderator]
You may want a few samples from other sources to solve the mysterious equals proliferation:
1,2,3,equals:
=
==
===
Mathematica expressions with equals (I give results as well so you can check output easily):
s = NDSolve[{y'[x] == y[x] Cos[x + y[x]], y[0] == 1}, y, {x, 0, 30}]
{{y->InterpolatingFunction[{{0.,30.}},<>]}}
Reduce[x^2 + 3 x == 2, x]
x < 1/2 (-3 - Sqrt[17]) || x > 1/2 (-3 + Sqrt[17])
x == \[Pi]/2 || (5 \[Pi])/6 <= x <= \[Pi] || (3 \[Pi])/2 <= x <= (
11 \[Pi])/6 || x == (5 \[Pi])/2 || (17 \[Pi])/6 <= x <= 3 \[Pi]
{x, y} = N[{1, 2}, 20];
While[x != y, {x, y} = {(x + y)/2, Sqrt[x y]}]; x
1.4567910310469068692
Eliminate[{x == 2 + y, y == z}, y]
2 + z == x
My system info is below:-
Whilst on this topic do other people see a lot of strange character errors/misinterpretations as in the following example? I seem to get a lot!
