Pre-Cal Friday

The lesson on Pre-Cal last Friday was salty yet sweet. I find it salty because,the topic about coterminal angles was full of twists and turns,esp. with the pi part and the graphing part (the one with the rotation on it; until now i had a hard time answering it). On the other hand, i find the radian-degree part easy as a fried egg because,you'll just have to convert it vice versa.                           So,i implore your help,Mr.P and to you,guys to help me with the coterminal angles and the rotate-turn angle graph part. Thank you and have a nice day.
