Well, the time that it took is great, but the answers are wrong. Did you put the 30 degrees in as radians? I'm sorry if I didn't make it clear that they were degrees. That's the only reason I can think of why it would give back faulty answers, other than it's not programmed well. But if you regularly use it and like it then it would surprise me if it wasn't a quality program.
Should be T=46.2 and theta = 60 degrees, or 1.047rad.
You can verify that by doing it by hand, solving the first equation and then putting that number into the bottom one to solve for T.
(Although to convert from rad to deg it should be (number in rad)*180/pi not addition.)
Either way I will download and try out that solver since it is quick and see if I can make it work for me.
Edit: Funny that this is also one I've already tried out, but couldn't get it to work. (One problem was that I was trying so many of them at a time that I got overwhelmed and lost track of which was which and then got frustrated.)
Thank you! I really appreciate the response!
