Solve for Q

Q= sin^-1 1.5/9.8

I got 8.80 Is this correct?

I have a TI-30 calculator and to do the sin^-1 I pushed the 2nd button and then sin. I am not sure if this is correct.

If that is 11.5 in the numerator, no way. Sine cannot be over 1.0 ever. So arcsin-greater than one is nuts.

No it is sin^-1 (1.15/9.8)

This is arcsin(1.15/9.8)=

=arcsin 0.117=6.74 degr
