Incorrectly calculated integral.

[hp-zl]

Thank you for the clarification.

I thought that pressing Shift+Enter reduces the arguments to floating point form ( in this case: limits of integration and subintegral function), then....
Sorry, this is just such my musings.

By the way.
Maybe it would be worth considering whether to introduce elliptic integrals (F, E, Π) into HP-Prime in the next software update.
Maybe also Jacobi functions (even if only the three basic ones: sn, cn ,dn)?

Greetings.
