RE: Laplace Transform Bug??
Hello,
so does this mean the Prime does not always return an exact value in CAS mode? Is this a bug or just a matter of usage? I get a simelar issue with this line: solve(TAN(x)=1,x,(pi/2)..(pi/2)) It outputs: 0.785398163397 If i use the exact() command I get: (286602)/(364913) as the result. Basicly this is pi/4. The line above is not. It is almost. I think I wouldn't even care. But shouldn't it say the result ist pi/4 instead of a the fraction? Another thing that I noticed is that if I try this in degree mode I get 45° which is the exact answer I would expect. But the output changes there too if I do not use the exact() command. Using it exact() the output is: 45° Without: 45.° So there is a dot at the end. I thought I may share this little things. In my opinion this are no big bugs or something similar. Usually I would not care about something like this because I do not think I will ever have to use such precise numbers. Greetings
