I'm trying to use my Ti-Nspire CAS to solve a few equations for the variable theta and when I do I get some strange results. I've had this problem before and remember having to enter the equation into the calculator in a certain way, but for the life of me I can't remember what the format was.
Here's what I'm trying to solve. .15*cos(theta) = .26666667 + 9.81*sin(theta) I'm trying to solve for the angle theta and when I enter solve(….) into the calculator it spits out x=6.2831853071796*n1-0.011282597074317 or x=6.2831853071796*n1+3.1846768515479.
I've tried this in radians and degrees, no luck.
How can I get this to just spit out the proper answer, which should be 6.9999?
Thanks for your help.
