Best ResponseYou've already chosen the best response.0What you put into a trig function is an angle and out of it you get a ratio of sides. So the inverse of a trig function takes ratios of sides and gives you an angle! To make our lives simpler, I will do that: \[\tan ( \sin^{1}(1))\] See, that arcsine in there is giving us an angle: \[\theta = \sin^{1}(1)\] We can turn it inside out by taking sine of both sides: \[\sin(\theta) = 1\] So now what value of \(\theta\) gives us this answer? Once you figure this out you can plug it in based on our substitution to find out what \[\tan ( \sin^{1}(1)) = \tan(\theta)=?\]
