Applications of periotic functions

ex. An EKG test your heart beat it periodic cause it just keeps happening the pattern that is....

ex. tides going in and out

periotic funt one witch repets regularly over the same number of independent variable units

or it repets its self over same domain , predictability

most of our studie will be baiced on this refrence y- sin (x)

sin x in your calc on with radince on and put zoom 7 or zoom trig

#1 a value what dose it do?

y=sin(x)

singnasoidal function cos and sin funtcion = waves on the x axis

y=2 sin(x) a value contols controles the AMPLITUDE of the funtion /a/= amplitude measure the amplitude by median or amplitude =/ max-min divided by 2

wjat dose b value controle? controles the waves 2x will double the number of waves within the space provided

formula = b=2 pie over period

or period= 2 pie over b

go on rob blond cheack this out trans formation of cos and sin funtions

c value controles the phase shift or horizontal shift controles left or right movement

formula phase shift = -c over b

d vaue = controle the virtical shift

virt shift = d

y= a(b,x,c) d

first day will be easyier studie more for 2 nd day

first day worth 25 % and SECOND IS 75 %

mr. max computer not working today ..... exactly use pdf insted of cdf

today we did independent and dependent probability todat independent is you put what you took out back dependent you keep it out so deentent will change the probabity answer

i ve been sick for the last three days

i am now on excercise four i missed on tuseday when we learnt the parrallegram deal but i learnt it today this stuff is easy

the trangle methiod steps when do i use this method ... when vectors are stacked chronologically ... this means do this leg first then next leg... etc step one starting from some origin create a vector t scale such that the tail is on that origin. arrow head tail no arrow ... then square uo the vecrot head possition for measurment this mean square up the head to tail so you can measure the deal step three creat v2 v3 v4 v5.....etc and remember to square up the head to measure step four from the oragin creat thr resaltent Vr with arrow .. so the tail is on oragin and its head is on the last vector head

need to bring protracter ruler graph paper soon. we just did vectors on euklid vectors is very easy

today we learnt about tricks on our calc. Prn in your finacal calc , int and bal all in your financal part in calc but these wont work unless you have all the data in your solver

to day we learnt about debt

the last couple of days we have been working in personal finance. by using your excel program and calculator you can easily find your answers.

lernt about personal finacing today pretty easy stuff

sick last couple of days but i looked at the blog and sounds like i havent missed too too much just practising sequences

we did 5 questions today i think i well on my way to being good at this

yesterday i was sick so i got no clue what happened

we starting on sequences and serise exel is the most coolest deal ever we learnt serise today by using excel its very easy dont et sucked into the crappy way instead of doing skinny way 3.1*80=....-... 'do .969 * 80 ...

we were sapost to have a test today then we had an esembaly with gary doer so we had a choice of test of studie i studied

matrices you have to read and evaluat the question to see if it's ether a transition non directed dreced and al that stuff

exactly and at most are totaly diffrent most means adding matrixes and exactly is just one

the leason yesterday was pretty easy useing the powers to get your answers was pretty easy
