tests, pretests, keys, ect ect ect

Mr maks kindly gave us back our tests today and i did GOOD well better. lets not get crazy. but instead of 19% like last time i got a 42%!!!! woo hoo. this is good bc my goal was 30%. so as long as i learn this stuff by the exam ill be a happy girl. im gonna woerk on the pretest tonight and see if i can do these questions by MYSELF.

Another Work Class! ! ! ! ! !

Well now that i have a follower life is good. and its getting even better...MORE TIME TO PRACTICE MATH! that is good. test is still on thursday and i have got to get these assignments done!! because there is going to be a homework check and caity is right...the only assignment that isnt done will for sure be the one i get checked. so i better get on that.

Work Classsssssssssssss

Hey there. so its a work period as you may have gathered from the title. and i am trying to do the practice test for thursday this week. yup test again. i can actually know how to do some of this stuff...like sum/difference identities, finding exact values, making both sides equal the same thing...proving identities i think thats what its called, and double angle identiteis. im not very good at simplifying equations, or using extraneous roots. but at least i can do the majority of these things. awesome.

DOUBLE ANGLE IDENTITIES!!!!!

Yes...there are more. I understand how to use the new identities. Still liking this stuff. All it seems to be is plugging numbers into equations or identities in this case. And if you can solve the equations you're good to go. I am even starting to recognize identities which is just fantastic. yay.

sum difference identities :(

AHHHHHHHHH! that is how i feel. i dont know what thw heck is going on today. this is just hard. the new identities are simple enough..plugging in numbers. i can handle that. however... ... the question of "find the exact value of tan(75 degrees) was absolutely ridiculous. i still dont know how we got the answer.
Oh boy...

EXTRANEOUS ROOTS!!!!!!!

Ok boys and girls. so an extraneous root is something that seems to work but in reality does not work. the only way to find out which answers do not work is to do a check...with your calculator. sounds simple enough. but lets just wait and see.

SIMPLIFICATION TECHNIQUES!!!!

We learnt problem solving techniques for proving identities. There are 8. In order to solve these questions i think im going to need to memorize some of the basic identities. Otherwise im not gonna be able to do these in a million years. I guess i gotta try out some questions to see if i get it or not. We'll see... ...

TRIG IDENTITIES

Trig identities look like equations, and formulas that involve sin, cos, cot, tan, sec, and csc equalling each other. That was my 1st impresion of these things. But whats 'v' and 'u'!?!?!?!!!?!?

I like this. i enjoy plugging numbers into a fomula and finding the answer. and since i understand why all the basic identities exist i understand how to do the questions. And the "triangle, square, circle" illustartion definately made the most sense in why 1/tan(x)=cos(x)/sin(x). i think im gonna like this.

TEST 2

We had our 2nd test yesterday and im shooting for a 30%!!!!! lets cross our fingers. my goal is to get a better mark then the last test....

TEST RETURN... ...

So we got tests back today...and i did about as good as i thought i would have done. However i think that tomorrow the test should go a little bit better because even though i dont know the new stuff i will be able to get marks on the old material. Thats the fabulous thing about cumulative tests.

HOMEWORK CHECK!!!!!

Today we did a homework check on exercises 1-10 and i...was not done. It would have been alot better if i had been done a few questions on each lesson because then i would at least have gotten partial marks..but oh well. Note to self...do the questions i understand!
Now im gonna go do accelerated math because i foiund that doing accelerated math helps a bunch for preparing for the tests.

RECIPROCAL FUNCTIONS!

Reciprocal is easy to understand because all it means is A/B becomes B/A. so when a function has a reciprocal all it means is 1/f(x) instead of f(x)/1. Im not sure how to find the asymptotes but i do know that when you know where they are you start the function going the opposite of (lessering/greatering) and do it pointing toward the asymptote without crossing that line...if that makes any sense. it kinda does to me. I just need to figure out how to know where the asymptote of the function is.

REFLECTIONS!!!!!

F(x) to -F(x) flips across the x-axis and thats great. its about the only one i understand because the other ones have no patterns to figure out the new functions. oh well.

HORIZONTAL/VERTICAL STRETCHING AND COMPRESSING!!!!

So every number being used is backwards of what i would normally think. like if something is 1/2 its actually bigger, and 2 it becomes smaller. so that will take awhile to get ised to. but so far so good. this doesnt seem like rocket science so i think everything should go not too badly. if the number is outside the brackets that means its "A" and its a vertical stretch or ompresion and if the number is inside the brackets its "B" and is a horizontal stretch or compression.

TRANSLATIONS!!!

I understand the new stuff from today about transformations and what formula to use in order to move functions around on a graph. the formula is y=f(x-h)+k...where h moves the function left to right and the k moves it up and down.
