    Does anyone know how to change the format of the answers given in the scratchpad? For example, when converting degrees to radians, ##177^{\circ}(\frac{\pi}{180})##, I want the calculator to give me ##\frac{59\pi}{60}## instead of 3.08923. Any help would be appreciated! This has been really annoying me...

    It depends on how your calculator works. What happens when you input [itex]\pi[/itex]?

    I get 3.14159. And, of course, I can change the decimal places given with settings.

    Thanks @Psinter I tried that already. However, instead of ##\frac {59\pi}{60}##, I get ##\frac {5949124}{1925761}##.

    Yeah, I didn't get CAS because CAS is "computer algebra systems" and it's not allowed in major tests like the SAT whereas the CX is...

    To add to that, ##\frac {5949124}{1925761}## is just ugly and I first thought it had to do with radians (not sure why), but no.

    A quick search revealed: https://tiplanet.org/forum/archives_voir.php?id=1884&play=

    If you check the gif sequence of screenshots you see that for [itex]cos^{-1}(-\frac{1}{2})[/itex] it gives the result in exact form [itex]\frac{2\pi}{3}[/itex] and in approximate form 2.09....

    It is in another language though.

    You know, forums like that just make me appreciate PF so much more :smile:

    Thanks for the link, Psinter, although it does not really show how to change the settings. I think I just have to do resort to doing those conversions with paper and pen. It's shame, though. For the price its worth, you'd think that the thing would clean for you.

    I think that's because it's a library that you load there, not something that becomes part of the operating system. But once again, I don't have that calc. I think the gif shows how to make it work.
    Meh, that happens. :biggrin:

    Ok, I'll look into it more. The Spanish made me dizzy...
