drawing graph of functions...HELP!!

ok, i am going to admit i am TERRIBLE when it comes to drawing graphs of functions. I have no idea what i am doing and kind of need a step by step approach. I really want to learn the best way of doing this as its now a big obstacle in my course.

The question i have is basically plot a graph of the function y=fr(x)
Im told that fr(x)=1.5/sin(x)
the domain is (0,1/2*$$\pi$$)

I already have an answer of what the graph SHOULD look like but am having trouble getting together a table of values to draw it with for myself. I have tried on my calculator but it keeps giving me a parallel line of y=1.5 (if that makes sense)
i know i must be putting it in wrong

HELP....!!

What values are you putting in for x? Is your calculator in radian mode?

Well, if you always put in the same x, you will always get out the same y!

Put in a number of different values for x between 0 and $(1/2)\pi$.
