Question

SOMEBODY PLEASE HELP ME? LAST TWO
How can a trigonometric function be chosen to model periodic phenomena with specified amplitude, frequency, and midline?

How can the unit circle be used to apply trigonometric functions to all real numbers?

Answer 7

periodic functions are repetitive. The same things happen at defined intervals... such as ocean tides, the wavelength of different types of light.

The sin curve and cos curve have the same repetitive characteristics.

so curve such as

y = asin(bx) + c

has an amplitude a, period 2pi/b and centre line c

thats my best guess

Answer 12

srry im not familiar with this stuff

Answer 13

okay thank you @Oceans @campbell_st

Answer 14

do you know ,, @camerondoherty @chrgarre12 @digitalmonk @dsood15

Answer 15

do you know how i can "Word" it, how to start off the sentence @campbell_st

Answer 16

y(t)=A.(cos(w.t-kz)), A is the amplitude, w the frequency in radians/s, and k is the wave number(2pi/lambda)

Answer 17

So many tags @_@

Answer 18

well here is an interactive unit circle

http://www.mathsisfun.com/algebra/trig-interactive-unit-circle.html

it shows that sin is the ratio of y/1 cos is x/1 and tan is the slope of the tangent at the point..

play with it and draw your own conclusions.

Answer 19

how can I word it, I already told my teacher that, and he wants to know how can I word it into words... a sentence. @RaphaelFilgueiras

@Hero @Here_to_Help15 @Nurali

Answer 21

the sin(w(t))=sin(w.(t+T)), were T is equal to 2pi/W, then, the sine function is periodic, if you are using that to model a periodic phenomena, higher W will implie in a small T, so the periodicity is "faster"

Answer 22

how can i start it off?? @RaphaelFilgueiras
