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?

    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
