100
What is 100 degrees in radians?
5π/9
100
What is the Cos of 45 degrees?
Square root of 2 over 2
100
What is the Amplitude in the equation y=6sin2(x-5)+9
6
100
How would the amplitude of a regular y=cosx graph change in the amplitude was changed to y=2cosx
The height of the cos wave is 2 times taller.
200
What is 7π radians in degrees?
1260 degrees
200
What is -225 degrees in radians?
-5π/4
200
What is the sin of 180 degrees?
0
200
What is the vertical shift in the equation y=3cos4(x-pi)-5
-5 or 5 down
200
How would the graph of a regular y=cosx graph change if the equation was changed to y=cos(x-3)
There would be a phase shift of 3 which means the graph would slide 3 units to the right
300

2pi
300
How would the graph of a regular y=cosx graph change if the graph is altered to y=cos(x)+5
The original cos graph would slide 5 units up
400

6.458 radians
400
What is tan of 45 degrees?
1
400
What is the phase shift in in the equation in the y=3sin(x-pi/3)+2
pi/3 or pi/3 up
400
How would the graph of a regular y=cosx graph change if the equation is altered to y=cos(x-pi/3)+6
The graph would shift pi/3 units to the right and 6 units up.
500

Negative square root of 3 over 2
500
What is the amplitude of the equation y=27sin2(x-pi)+2
27
500
How would the graph of a regular y=cosx graph change if the equation is altered to y=6cos(x-pi/3)-1
The graph would get as high as 5 and as low as -7. With a slide of pi/3 to the right and a slide of 1 unit down.
