how do i enter sec^-1(5.9963) in the scientific calculator on this site. I can see it in light grey in the top right hand corner of the sec button, but I can't figure out how to select it.
+118723 $$\\sec^{-1}(5.9963)\\
=cos^{-1}(1/5.9963)\\$$
now you can just enter it into the sit calc as
acos(1/5.993)=
and you will get your answer
Make sure the calc is set to degrees (or radians if that is your preference) there is a button on the bottom left for this.
ALSO
acos stands for arc cos which is the same as inverse cos.
