Hi all, My math is kinda weak but I'm re-attempting a precalculus course . I was just wondering exactly how the unit circle helps me?? I mean,I can generate it quite easily(from memory,but)...but why not just convert to degrees and enter it into my calculator? Also,finding angles that generated a tan value is so tedious...any tips?(I havent even attempted csc,sec and cot yet) I'm glad I stumbled across these forums!
