+6 Hey everyone.
I was doing a problem ( 12 sin45 = 8.485281374244 )
This is fine, but I was told the right answer was 6*sqrt2 , which does equal the same number.
How do you change the first answer to be like the second? Its too long of an number to even know where to start!
+33661 sin(45°) can be written as 1/sqrt(2), which, in turn, is the same as sqrt(2)/2, so 12*sin(45°) is 12*sqrt(2)/6 or 6*sqrt(2).
+6 thanks for the reply.
So if sin(45°) is sqrt(2)/2
How is 12*sin(45°) = 12*sqrt(2)/6
Should it not be 12*sqrt(2)/2 ?
