This was written in April. I have now finished the digitization of Examples from Chapter 4 of Timofeev's book; the algebraic integrals and model solutions are appended below. Timofeev presents 132 Examples in Chapter 4, of which the final group (numbers 123 - 132, p. 198-200) are mere substitution recipes that had to be omitted here. With each Example consisting of just a single integral, 122 entries result in total.
As in the digitization of other Chapters, nested powers (^r)^(1/s) were interpreted as ^(r/s), with the exception of Example #1 (just for the sake of variety). The correction of misprints was straightforward, apart from Example #53 (p. 164) where the x dependence of the terms in Timofeev's evaluation corresponds with the integrand denominator, while their amplitudes are incompatible with the integrand numerator. No simple correction of integrand and/or antiderivative appears feasible here, so the integrand was adopted as printed while all the amplitudes in the antiderivative were changed.
For the default setting of real variables, Derive 6.10 is found to fail on Examples 13, 15, 17, 20-21, 35, 37-42, 49, 51, 53, 74, 76, 99-100, 107-108, 110, 112-114, and 117-122; additionally it cannot evaluate Examples 14, 16-21, 23-27, and 46 if the integration variable (and the occasional parameters) are declared complex.
Timofeev's book can hopefully still be found at:
