Trig Calculation Question

  1. Apr 10, 2012 #1
    Hi,

    I have a simple question i am working a tension query and need to do some trig calculations. I know the equation i need is below.

    θ = Sin[itex]^{}-1[/itex] 0.6/3

    When i type this in the calculator as shown above i get an answer of 12.29 although when i enter it in the calculator using brackets around (0.6/3) i then get an answer of 11.54 which one would be correct? I just need to ensure i am entering into the calculator correctly.

    The answer depends upon whether you are looking for [itex](sin^{-1}0.6)/3 [/itex] or [itex] sin^{-1}(0.6/3) [/itex] I suspect you are looking for the latter, are you??
