sine arc function?

-----------------------------------

Hello...

I was wondering if turing has a predefined sine arc function (I need it in degrees)

the sind function only returns the ratio, but it's the angle that I want. I'm not sure my wording is the best, so I'll provide an example

sind (30) would return a value of 0.5, however, I"m wondering if there's an arcsind that woudl allow for

arcsind (0.5) which would return 30.

Thanks for all your help

you know arcsind does work.

if not that then you could go arcsin*(180/pi) to turn radians into degrees

What I forgot to mention is that, 

arcsind

works for Turing 4.05 only.

older versions

-----------------------------------

I have an older version of Turing.  I plan on getting the newest one but I need to get this done.  The version I have does include an arctan function.  Is there any way to manipulate trigonometric functions so that I can use a combination of arctan and other functions to get arcsin?  I can't see a way of doing this with Taylor series expansions.  Maybe I should be thinking about using exponentials and complex variables (but leaving 'i' out of it)?

Disclaimer:  I am not a Math major.  The furthest math I took was 1st year intro calculus.  I don't really like math all that much - but I am quite capable of it.  Take this proof with a bit of salt, and perhaps oregano for taste.

I'll going to work in radians, because I want to and because all the cool people do so anyway.  You've already seen a way to convert from radians to degrees above.
Conversions from arctan to arcsin are possible, but you'll just have to limit yourself to (-1
