## Homework Statement

sec(5x)-5=0

## Homework Equations

## The Attempt at a Solution

I turned it into 1/cos(5x)=5 x=θ/5

then i switched it to cos(5x)=/1/5

Then cos

^{-1}(1/5)=θ which = 1.36 (one solution) then divided by 5 which is .2738 which works as one solution

since the positive cos is in the 1st and 4th quadrant i need to subtract 2pi to 1.36= 4.91 then divide by 5 which gives me .9827 which also works

But i am stuck after that
