sry the answer (A) is correct but (b) is wrong
so what is the answer
kindly tell me
(b) by solving we can get
cos(360-60)-sin(360-60)
cos60+sin60
1/root2+root3/2
(root3+1)/2
cos(360-60)-sin(360-60)
cos60+sin60
1/root2+root3/2
(root3+1)/2
hmm...
my mistake
a known mistake is better than an unknown truth
