Ticket #12731 – Description
v9 v35 1 1 Maxima'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 4 4 * #14591 cosh integral incorrect because of abs_integrate 5 5 * #16643 integrate() infinite loop 6 * #17183 another abs_integrate error7 * #17468 log(abs(sin())) problem8 * #17511 abs(sin(x)) and abs(cos(x)) are flatout wrong6 * #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 9 9  10 10
