find all the values of x at which the function fails to be continuous
f(x)= 2/(1+cos2x)
I believe the function fails to be continuous when the denominator equals zero(right?)
So wouldn't the correct answer be 2n(pi)+(pi/2) for all integers n? The answer keeps coming up as incorrect.
Could someone please correct me if I'm wrong?
Thank you! I appreciate the help!
