If asinx+bcos(C+x) + bcos(C-x)= α,then the min value of |cosC| is 1)underoot((α 2 -a 2 )/b 2 ) 2)underoot((α 2 -a 2 )/4b 2 ) 3)underoot((α 2 -a 2 )/16b 2 ) 4)none

If asinx+bcos(C+x) + bcos(C-x)=α,then the min value of |cosC| is 
1)underoot((α2-a2)/b2)
2)underoot((α2-a2)/4b2)
3)underoot((α2-a2)/16b2)
4)none
