```							no there is noo need to post a new image. the above image is too clear.B and C lie in 0 to 3pi/4, so by usual rules of inequalities, B-C is bound to lie in -3pi/4 to 3pi/4.now cos(B-C) will attain its max value 1 at B-C=0.and it will attain its least value -1/root2 at B-C= +-3pi/4 [this is clear from graph of cosine]hence it lies in between -1/root2 to 1
