How do you put in the calculator sin square 30

Thanks so much Webby but I keep getting a heeps small answer

Or recognise the 60^o, 30^o, right angle triangle with sides 1 unit, 2 units and root 3 units long.

Then sin30^o = 1/2

So sin²30^o=1/4



Hope that helps

Oh and there is never such a thing as a stupid stupid stupid question. If there is something you don't understand you can never get an answer without asking

Ask away. :uhhuh:

im pretty sure (sin 30)(sin30) should work

½ x ½ = ¼
