Around the Benz

Take a look at this photo I found at Flickr. It got me thinking: "Wow! Look; there's the unit circle!". Then I started wondering.....
  • How big are each of the angles, in degrees and radians, in the picture?
  • What standard position angles are being pointed to in the image?
  • What negative standard position angles are being pointed to?
  • What are the coordinates of those points in the unit circle?
There's math all around us folks! ;-)

well, in class today, i remembered more of the unit circle than i thought i would have, so i guess reviewing it really does help retain the info if you review notes every night. don't want the forgetting curve to reach zero. and i also went to the site for the hypotenuse mr. k was talking about... here's the site! and i found the comic to be pretty funny, have fun! =)

If you like the comic leave Ken a comment; he'd love to hear from you!

hey guys, well i finally realized that i changed my password sometime in grade 11 and it took me a while but i figured out my password. so i decided to blog now and not wait until the day before the test. anyways, as i was doing today's assignment a lot of things came back to me even though i took this course last semester. i'm pretty good at html and maybe i can put something up in the near future. see all of you guys tomorrow =)

this is my first blog. i didn't know how this works at first, but in class mr. k explained it perfectly. so here i am writing my blog. i had no clue on what to do on the mental math. reason for that is i wasn't in class the other day. i did some studying and borrowed the notes for that day and now it makes sense. hopefully i'll do WAY better in the next mental math. take advice from me...don't miss class unless its really important!

hey mr k!.. well this is my 5th attempt to sign on this site and it finally WORKED! Class was very interesting today because I finally understood most of the math you taught us. However, I am unsure of some questions but i will for sure go to you sooner or later. :)

sorry about that first blank comment.. i was about to answer mr. k's questions about the "benz" and basically i'm assuming that if the unit cirlce is lying on top of the benz we can assume that the left arm falls into 7pi/6 or 210 degrees and that the right arm falls into 11pi/6 or 330 degrees right? and we can definitely say that the middle arm makes a 90 degree angle or pi/2.

so how can i say that the left and right arms fall into those units basically b/c i tried playing with the picture and believe me it works.. (the benz) hey if you dont believe my crappy picture you can always try and imagine the arms repeating itself over and over again. and it'll still fall in the same spot.

if it's asking for negative postions by ASSUMING AND IMAGINING we can say that the left arm is -5pi/6, middle arm is -3pi/2 and that the right arm is at -pi/6.

i really wanna right the coordinates of the points to answer all the questions but unfortunately it's hard to get your point through if you cant write the symbols like square roots and fractions and stuff. so to make our load a lot easier you can refer to our notes in "Exact values in the unit circle".

haha.. that was pretty long.. sorry about that. ohh and hey i know i might've made some errors or maybe my whole assumption is wrong but what the heck just tell me, i basically did this to see if i did understand the lessons we had today and yesterday.

So mr. k, can we consider this as a blog? yes, no, maybe? let's talk about this tomorrow!

i think my mom thinks im crazy, as i was doing my homework tonight i had my arms going in a circle to make the unit circle and i was talking to myself outloud, and counting then i lost count so i started laaaauughing - i thought it was funny =| . shes like uhhh rach what are you doing? i started laughing and i was like my homework. she starred at me like i was crazy and walked away. haha oh well. i had such a blonde moment today in class, i was aruging with allison trying to prove to her that 1 divided by 0 is one, but she was like uhh no its undefined. dont know HOW i forgot that one but oh well, haha opppps. i had a brain fart. hopefully that doesnt happen to often. but yeah. looking forward to tomorrows class =)

This isn't directly related to the class but its a very challenging puzzle i have found. I'm yet to solve this but maybe someone from the class will be able to. Here it is http://www.transience.com.au/pearl2.html.
If anyone figures this out I would like to know how.

hmm adrien that puzzle isnt hard.. it look me about 5 minutes to solve. in order to beat that, all u gotta do is make sure its a even ammount of balls on his turn. if u can do that, whatever he does, copy him and u'll win. pretty hard to explain, i guess u gotta find out by doing it.. good luck? not sure if this is any help but it is possible.

See the thing is i have figured out how to do this puzzle. as it was hinted by Mr. K that it deals with binary code. but in a general sense this is a very complicated simple puzzle. As the majority of people will not understand or figure out that this puzzle deals with this. Also most puzzles have simple solutions but they are hidden very well which make sthem good puzzles.
