Waldek and martin wrote about trigcat : I read (and understand) each argument pro and cons, but I find very important to get the right draw in
draw (asin sin x, x=-10..10) draw (acos sin x, x=-10..10) So I vote to remove the default rewrite rules asin sin x = x and others. Then in expression asin sin x remains and a function normalize (or rewrite) may be add to transform asin sin x in x only if the user wants it. Then I see the question : Is asin 1 = %pi/2 remains in expression ? It's the choice of (all?) other cas, and usual mathematic... But this implicitely gives notice a branch-cut. Or asin 1 lets asin 1 and we need an other rewrite/usual-normalize- branch-cut function that get %pi/2 for it. I hope it's possible to improve the actual result for this command : [asin sin (k*%pi/8) for k in 0..100] François --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "FriCAS - computer algebra system" group.
