Find the amplitude feature for the sin graph of y=f(x) 1)amplitude 2)period 3)phase shift 4.)the domain/the range 5.)x/y intercept 6.)the equation of the graph
|dw:1372972278692:dw|
i know the amplitude is 3 but how do i find the others by looking on te graph
The amplitude is half the difference between the max value and min value. The max value here is 3 and the min value is -3. So A=(3--3)/2=3. The period is the time it takes for the graph to complete one cycle. Here, it completes one cycle between negative pi and pi, so the period is 2pi.
not sure if they count shift in up and down as phase shift too.. but theres no phase shift in your problem anyway, as it hasnt moved up or down or left or right
so the period would be -pi minus pi?
period is the length between these 2 points
that is the start and end points u are giving me for 1 oscillation what is the length?
oh 5 so i exclude my starting and ending point?
lemme ask you simpler question... what is this length|dw:1372973193523:dw|
you know pi is just a number right is that what is confusing you pi = 3.14159263.....
i dnt know why im not undertanding would it be -2? i did -pi/2-pie/2
okay can i ask you 1 thing
whats the distance from the middle
these are not trick questions lol
i would say 15 is b/w it ...
what is half of the rule distance?
okay maybe we need to work with smaller numbers...
do u know a site that has similar examples ?
what is the distance between point 1 and 2?
okay so that means there was 1 added to 1
so that distance there is 1... DO YOU GET IT??
wait can you see my drawing?
umm okay.. now what is this distance ur gonna have to start answering faster or this will take forever
so how long is this whole line?|dw:1372973851072:dw|
amazing u are like a genius
lengths in between there?
im not sure i dnt wanna write the wrong thing
theres ur problem.. ur too afraid to do math
you cant learn like that... everyone will make mistakes, but they have to learn from it
lemme show it to you another way
what is the total length of this line?
okay, so u see me writing from 0 to 2 or -1 to 1 they were both length 2
okay let me rephrase question
there is 1 for each side
what is the length of the left side
can something be negative units long?
what is the size ? of that line
