ex 10

hello...so today in class we learned how to graph inverse functions...in class it seemed easy when Mr. K went over it ....but as I was trying to do exercise ten I realized I was lost....and I was wondering if we could go over a couple questions from exercise ten...I don't know if I'm the only one...but anyone feel free to comment on this..thanks

Muddiest point..

Alright so for this weekend's muddiest point I encountered problems with question 15 on exercise 5. I also don't understand on question 3 why it is just
k(pi) and not written as 2k(pi). Also do you always have to put +- in front of the answers or do you always put 2k(pi)? My last question is for 14. I had figured it out with my calculator in degrees to 5.173. The answer is 51.73, but this is the answer with my calculator in radians. From the question, how are you supposed to know if your calculator is supposed to be in degrees or radians? So that's my muddiest point, comment this to help or add your own muddiest point.

homework ex. 4

Okay, whoa! haha. I do not know how to do number 16 and I'm pretty sure I'm not the only one. I was working on it with John earlier and we understand that it's pi and pi/2 but we do not know how to get the answers that were in the exercise book. =S...So if we could go over this in class it would be most excellent and greatly appreciated because I was doing my math, I understood everything until bam! 16! my favourite number! bee tee double you [btw-by the way] has stumped me! Okay well I am done with this post and fellow classmates feel free to comment on this with your problems or just your opinion. =Þ Bye, have a good night/evening and thank you! [my favourite colours! WOO!]

Homework Check...

Hey, I thought it would be a good idea to have a post every night, that anyone can post, dealing with the questions the class is having difficulties with. The first person to post it will put their questions in the post and everyone else can then further put any other questions in as comments. Mr. K would then have an update every night on what we are all having difficulties on before the beginning of the next class. This way he can prepare or set aside a time to explain them. I hope to hear all of your opinions on this tomorrow, including of course Mr. K's.
P.S. Question 5-as to why we divide y or x by the value of each side of the triangle. As well as questions 8,10, and 11. (exercise 2)
