  • Ticket #12731 – Description

    v9 v35  
    11Maxima's `abs_integrate` contributed package gives us lots of nice new integrals, but also really breaks a lot of stuff, apparently.  Add to this list as you see fit:
    2 * #13733 (fixed but note unwanted interactions)
    3 * #11590 sgn() function (not reported upstream?)
     2* #13733 Incorrect integral in Maxima
     3* #11590 Integrating the sgn() function can produce incorrect results
    44* #14591 cosh integral incorrect because of abs_integrate
    55* #16643 integrate() infinite loop
    6 * #17183 another abs_integrate error
    7 * #17468 log(abs(sin())) problem
    8 * #17511 abs(sin(x)) and abs(cos(x)) are flat-out wrong
     6* #17183 Yet another abs_integrate trig integral problem
     7* #17468 Strange integration error/hang with log(abs(sin(x)))
     8* #17511 Get integral of abs(sin(x)) and abs(cos(x)) right
