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
