Calculator issue
« on: May 20, 2015, 10:18:42 pm »
Sorry for posting again. But both of my calculators are being dumb, and I want to know what's wrong with them.
They're both in degree mode, yet when I type in csc(pi/6) it equals 31.57396133. When in my book it's telling me two. Same with Google. Does anyone know why my calculators are doing this? The only thing that seems different is that the Google calculator is saying, csc(pi/6radians) Which I have no clue what's going on there.

You should have the calculator in Radians. things like pi/6, pi/4, pi/2, ect... are radians. You would use degree for problems like csc(50) where 50 is 50 degrees

It should look like this

csc(pi/6) = 1/sin(pi/6) = 1/0.5 = 2

Hmm, I am sorry then, I am use to doing these problems in my head(memorization of the unit circle). That was the best I had to help, maybe someone else can, sorry

I figured it out, you're using inverse sin instead of using sin then doing 1 divided by your answer

Dont use the Sin()^-1 thing, use Sin() then do 1/ the answer you get from sin()
