Homework Help: Math

Posted by Anonymous on Sunday, November 25, 2007 at 2:25pm.


*Note - We have to find the exact value of these. That I know to do. For example sin5π/12 will be broken into sin (π/6) + (π/4)

sin 5π/12
sin (π/6) + (π/4)
sin π/6 cos π/4 + cos π/6 sin π/4

I get all those steps. The part I am struggling with is breaking these into 2 simple ones.

a) sin 11π/12
b) cos 13π/12
c) tan (-7π/12)
d) tan (-5π/12)
