Quote: what do you do when your have to sin 40degree30 minutes what do that do when you get the anwer
not real sure what you're asking here but I'm going to guess you want to know how to convert
40 degrees 30 minutes to just degrees so you can punch it into the calculator
think of 1 degree as 1 hour
there are 60 minutes to an hour, there are 60 minutes to a degree
there are 60 seconds to a minute in both cases.
so 30 minutes is 30/60 = 1/2 degree
so 40 degrees 30 minutes is 40 1/2 = 40.5 degrees
and you can just punch in
4 0 . 5 sin =
to get the answer
+6251
