Question

solve on the interval [0,2pi)

2 sec x +5=1

Totally lost here

Answer 1

Can you isolate the sec(x) part?

Answer 2

I've tried. I'm just really not sure as to how. My teacher never really explained the how to, and the book is about as useless as they come.

Answer 3

sec x = -2
hence for what deg between 0 and 360 would this be the case
sec is according to the trigonometric table, 2 at sec 60

hence if sec 60 = 2, then sec (180-60) or sec(180+60) would give you -2
