# solve sec(x) = - 5 Watch

1. Hi,

To solve sec (x) = (-) 5 you would have to look at it as 1/cos (x) = -5 then doing cos (x) = - 0.2 but I'm not sure what you do from here to find all the values between the interval 0<x>2(pi) in radians

Thanks
2. cos (2pi - x) = cos x

Now using the method(i.e. cast/graphs/general solutions) you prefer, find the other solutions in the given range.
