Otherwise, do you know of an online calculator or solver, or something like the TI-83 Graphing Calculator that would convert this?

Thanks,

PS

This seems to be essential for pre-calc, calc, and trig problems, but I haven't found an answer after several hours of searching on the Internet. Thanks for the help.
