I have been working on this problem forever, and I finally decided to seek help. My first thought upon seeing this problem was to divide both sides by csc(theta) leaving the equation as sec(theta)=csc(theta), but that isn't the right answer. For some reason the answer seems obvious, but I can't find it. Can someone help me please?
I really want to work it out myself, but can someone just nudge me in the right direction?
