An example I'll use is sin 45deg + cos 60deg.
While studying from my book, I notice that they refer to tables in order to turn these expressions into real numbers. My trig class has just begun and I haven't remembered these tables and I am not allowed to use notes during quizzes. Is there another way to find these expressions without having to look up a table? I need to find out that sin 45deg = ?2/2 on my own, for example. I can find some such as cos 180deg easily just by drawing it on my own and finding that it equals -1, but not when it comes to square roots or fractions. Help is appreciated
"It's quite simple."
Ok.
"A lengthy explanation for a process that takes no more than 30 seconds. If you have to memorize values for the basic angles, as someone suggested, then you aren't truly understanding how trigonometry works."
Whoa! Pompous f aggot alert. Isn't it obvious that I am not understanding it if I come here looking for help? How stupid are you? There's academic smarts, and then there's common sense, retard. I put up with far too many of you quintessential overachievers in class. Thanks for help, douchebag.
