Okay, so this time we're going to use radians instead of degrees.
00:06
So we have to start off with find any of the p.
00:10
So we're going to start off with this is x and this is y.
00:12
So this would be the hypotenuse and this is opposite.
00:17
So opposite and apotenuse, let's do sign.
00:19
So sign of pi over 8 equals x over 34 .5.
00:28
So 34 .5, sine pi over 8 equals x.
00:37
Now, you're going to put that in the calculator.
00:39
Make sure you're in radiance and not degrees.
00:42
If you're in degrees, go to your mode and change it to radiance.
00:46
And that gives you in radiance 13 .2 decimal places to zero.
00:57
Now to find y, we're going to use cosine...
