Find Tan pheta if sec pheta= 5/2 and 270 degrees is less than or equal to pheta which is less than or equal to 360 degrees
-------------
First time I've seen pheta. It's probably theta, a Greek letter.
-------------
sec(p) = 5/2, 270 <= p <= 360
cos(p) = 2/5
-----
sin%28p%29+=+sqrt%281+-+cos%5E2%28p%29%29+=+sqrt%2821%29%2F5
tan(p) = sin/cos = sqrt(21)/2
In Q4 --> -sqrt(21)/2
