1. The csc^1(1.23)
I got 1.061 in radian mode
2. Cot^1(2.26)
I got 0.8240 in radians
3. Cos^1(0.84)
I got 2.568
Are these correct?

drwls,
Only your answer to #3 is correct
The tangent of 0.824 radians is 1.0804, and the cotangent is 0.9256. not 2.26
The sine of 1.061 rad is 0.8728 and the csc is 1.1457
