Domain- What x's are you allowed to put in Range - What y-vaules can the function spit out

OpenStudy (eyust707):

We are allowed to put in any x value

so for domain & function what would i put?

OpenStudy (eyust707):

Domian- Any value of x... All real numbers

there will be no amplitude since there is no maximum value of y so amplitude= none, period = 2*pi/2=pi

OpenStudy (eyust707):

oh wait the range is acutally all realls as well

domain = any value of x

vertical asymptote are x= pi/2, -pi/2

thanks sweetie :)

as you can see there are y values from -infinity to infinity

yea it's correct range is all real numbers

I still don't understand exactly how to find the period can you please help break it down.
