Subject: integration test suite / Chap 3
These are the excercises for Chap 3 in Timofeev's book,

p.101 #1 - #3, p.105 #4 - #9, p.109 #10 - #12, p.113 #13, #14

Two of them are 'reductions formula' for a linear term, #4 and #5.

For those I have no idea how to test with Maple - they should be

done by partial integration and thus I ignore them.

The others seem to be for applying decomposition using partial

fractions. For which I suppose, that all CAS do it. There seem

to be no sophisticated cases there, so I just state _some_.

Maple 17 do them all (and I was to lazy to check for typos in

the results given in the book):

L:=[

#7

Int( (2*x-3) / (3+6*x +2*x^2)^3,x),

#9

Int(1/(x^2+3*x+2)^5,x),

#11

Int(x^9/(x^2+3*x+2)^5, x),

#12

Int((1+2*x)^2/(3+5*x+2*x^2)^5,x),

#13

Int( (a-b*x^2)^3/x^7,x),

#14

Int(x^13/(a^4+x^4)^5,x)

];

Now let the system evaluate, differentiate w.r.t. x and let

it check, whether the integrand is recovered:

map( t -> diff(value(t),x) = op(1,t), L);

simplify(%);

map(is, %);

[true, true, true, true, true, true]

Sorry for a non-complete treatment.
