Answers

1
In relation to the function shown, which of the following options is correct:
The value of C affects the vertical stretch
The value of D is the amplitude
The value of A affects the midline
The value of B affects the period.
2
Given the coordinates (1/2, √3/2), we can tell that:
Cos is (1/2)/(√3/2)
Cos is √3/2
Sin is (√3/2)/(1/2)
Sin is √3/2
3
The difference between the graphs of y= cos(x) and y= sin(x) is:
y= sin(x) is an inverse of the graph of y= cos(x)
y= sin(x) starts at the mid-line, while y= cos(x) doesn't
The periods differs by a factor of (pi/2)
y= cos(x) has twice the amplitude than y= sin(x)
4
(sec x) / (csc x) can be expressed as:
tan x
only (sec x)/ (csc x)
(csc x)/(tan x)
cot x
5
If the black graph is y= sin(x), then the the red and blue graphs are, respectively:
y= (2)sin(x), y=(-2)sin(x)
y= (0.5)sin(x), y= (2)sin(x)
y= (2)sin(x), y= (0.5)sin(x)
y= (-2)sin(x), y= (2)sin(x)
