Question

provide an example of a trig function and describe how it is transformed from the standard trig function of f(x) = sin x.

Answer 1

well, there are 4 ways to transform it, do you know what they are?

Answer 2

i cant remember i tried finding them in my class but i dont think they are in my module

Answer 3

been looking for 20 min lol

Answer 4

while sin x is commonly used, it leads to confusion. sin is the name of a function, just as 'f' is the name of a function:

f(x) = sin(x) is a better rendition.

and we just went over 3 of the transformations in an earlier post.

Answer 5

period vertical and amplitude?

Answer 6

yep, phase shift will be the 4th. i dont think they want all 4 tho

Answer 7

i knew vertical and amp but i didnt think period was one

Answer 8

can you modify the period of the function?

Answer 9

yes

Answer 10

then its a transofrmation

Answer 11

ahh ok i get it

Answer 12

sin(x) is not the same graph as sin(x/3)

Answer 13

why is that? is it because it transforms sin x?

Answer 14

yep.

sin(3) does not equal sin(3/3) does it? if not, then we have altered some property of sin(x)

Answer 15

ooh ok. im going to use this as an example lol

Answer 16

im also asked why the interval is important in trig functions. what is the "interval"
