[Please note that in some questions in the exercise above, you will find that now and then they have inserted an angle in degrees (the symbol gives it away) and so be sure to change the calculator modes accordingly. Especially one of the questions where they have written an angle as Pi degrees. They are trying  to trick you into thinking that it is a radian measure because of the Pi symbol except right after they give degree symbol. When there is no symbol then you should always assume the angle to be in radians.]

So folks, we should keep in mind one of the discoveries from today's class (and please do test this for yourself) that if the period of the function changes, then one can add and subtract the value of the period from the angles we get as a result of our calculations. Do the following for homework and don't forget to do some questions from the miscellaneous exercises of chapter 10 and 11.
