I know this may seem pretty basic but I really don't understand how to estimate these values. I need to know more about the process than just the answers, thanks!

sec 67.43 = ?

If csc θ = 3.164, then θ=?

ok thanks for your reply, and yes we are allowed to use calculators. But I'm not sure what you mean by 'θ = arc sin 0.316 (Press shift , then cos 0.316 )'. is that the sin with the little -1 (sin^-1(0.316))?

Also, is there a way to express this in terms of pi? - May 6th 2010, 11:40 PMmathaddict

Cool thanks. I didn't realize 1/sin had to be done first before using the arc sin. Probably will have more probs tomorrow, thanks again!
