What is the domain of validity for csc
OpenStudy (ddcamp):
This is asking where csc does exist. To find that, find where it doesn't exist and exclude those values. Basically, when is 1/sin(theta) undefined?
OpenStudy (ddcamp):
Which would be when sin(theta) = 0
OpenStudy (anonymous):
Ummmm idk...
OpenStudy (ddcamp):
Have you gone over the unit circle yet? Sin(theta) will be zero at (pi)n, so csc(theta) can not exist at any whole multiples of pi.
