Today everyone learned that numbers can be after a Sin or Cos or Tan but before the Theata (or under it).
Now everyone is have a bit of trouble understanding that the "solve within specified interval" doesn't mean you can't do more then one revolution. If there was a number in front of theata, (ill use 3 like we used today) the answers will be 3X smaller, so that means you can put 3X the amount of answers (so to speak). But this rule also happens vise versa, if theata is divided by a number, that means your answers will be 3X larger so make sure they all fit in the interval. Now I can't post any really neat-o pictures to show exemples of this because I'm posting this via phone, but Mr.Professor.Teacher.Piatek has a handy dandy wiki page that has all the examples you will ever need. See ya tomorrow!

PS: you know what I find funny? You can use quadratics on a trigonomic equation in a circle.
