Calculating an integral with Math. 5.2 and Math. 7.0

Posted 2 days ago

Ecuacion resuelta con Math 5.2 Pero la misma ecuación Math 7.0 NO puede resolverla, tiempo de compilacion 1.5 horas y nadaEcuación NO resuelta con Mth 7.0

This is a formula to obtain the Geometric Mean Distance of a rectangle (as area) with sides a (base) and b (height).

I've not changed the assumptions, I've separated them in an attempt to make the Math 7.0 algorithm better understand what I want to do.

I know that the inequalities are not fulfilled in the entire integration range but with Math 5.2 work properly.

Do you know if that has been changed in Math 5.2?

Anyway, thank you very much for your interest in answering my post.

Hi,

About "I've not changed the assumptions": I just meant that the assumptions in the two codes are different. The second code is missing the important one, a > 0 && b > 0 && a > b, at the time that Integrate[] is evaluated.

Integrate[] changes every version, I think. The exact changes are unknown to me.
