There are no keys for cosecant, secant, and cotangent. You can calculate those ratios as
csc(x) = 1/sin(x)
sec(x) = 1/cos(x)
cot(x) = 1/tan(x)
Simply calculate the trig ratio on the right and then take its reciprocal.

It is very likely that when you change the angle unit, you are not saving the changes made.
After you finish changing settings, use the TAB key repeatedly to move cursor towards the OK button at the bottom. If you do not confirm changes by clicking OK, they will be lost.
You can also make the changes the default ones by clicking the Make Default option.
