However, despite spending 40 years working on elliptic functions, Legendre never gained the insight of Jacobi and Abel and the independent work of these two mathematicians was making Legendre's new three volume work obsolete almost as soon as it was published.
Gayunman, sa kabila ng paggastos sa 40 taon ang paggawa sa tambilugin function, Legendre hindi nagkamit ng pananaw ng Jacobi at Abel at ang independent trabaho ng mga ito ng dalawang mathematicians ay paggawa ng Legendre ng bagong tatlong dami ng trabaho lipas na halos sa sandaling ito ay nai-publish.
