I should know this, But erk.
7pi/12*180/pi pi/12*180/pi cos 15 + sin 105
Oops. Sorry. I did not clarify: Simplify the following. the final answer must be exact. However, it isn't necessary to rationalize the denominator.

use angle identites for cos (45-30) and sin (60+45)
Sorry. I don't understand....
sincos sincos cos cos sin sin??
NotHello NotTim, sin(7pi/12) + cos(pi/12) cos(pi/2 + pi/12) + cos (pi/2)
NotSorry, sin(pi/2 + pi/12) + cos(pi/2)
Er, I still don't understand...
Wait. So am I doing the addition formula for both of them?
In that, I break both of them up?
Don;t do it my way, it's only gonna make it more complicated I thought I would be able to reduce it to Zero but Zero isn't the answer... shinigam1m is right!
sin(105) + cos(15) sin(60 + 45) + cos(45 - 30) sin60cos45 + sin45cos60 + cos45cos30 + sin45sin30
I think I m suppose to keep it in radians.
keep it in radians then 45 = pi/4, 60 = pi/3 and 30=pi/6
i changed my picture
