I'll use x instead of theta, will that be fine?

anonymous · Answer

the problem uses theta idk if that will change anything if you use x

solomonzelman · Answer

The variable is same. I never liked the unit sircle, but I'll give you the graph to look at for a second. https://www.desmos.com/calculator/z37jpt6i6s

my conncetion got murdered for a second.

solomonzelman · Answer

You can see the range is bounded to [-1,1] .

solomonzelman · Answer

domain is infinite.

anonymous · Answer

all good

solomonzelman · Answer

amplitude is 1, it is just the height of the graph.

anonymous · Answer

ok but um.. for amplitude and all those does the question mean I have to write out the definitions of each but I don't understand bout the circle thing

solomonzelman · Answer

The period 2pi.
every time the function repeats it's curve cycle.

connection is dang slow.
