How can I find c and d if 8 cos (theta - pi / 3)=c sin theta + d cos theta8cos(θ−π3)=csinθ+dcosθ? Precalculus 1 Answer Nghi N. May 28, 2015 cos (a - (pi)/3) = cos a.cos (pi/3) + sin a.sin (pi)/3 =cos(a−π3)=cosa.cos(π3)+sina.sin(π)3= = (1/2)cos a + ((sqrt3)/2)sin a=(12)cosa+(√32)sina = (sqrt3/2)sin a + (1/2)cos a(√32)sina+(12)cosa 8cos (a - pi/3) = 4sqrt3sin a + 4cos a8cos(a−π3)=4√3sina+4cosa Answers:: c = 4sqrt3 and d = 4c=4√3andd=4 Answer link Related questions How do I determine the molecular shape of a molecule?
