fracleft(sin(A)sin(B) ight)^2+left(sin(A)cos(B) ight)^2+left(sin(B)cos(A) ight)^2+left(cos(A)cos(B) ight)^2left(sin(A)sin(B)+cos(A)cos(B) ight)^2

HINT: you have an B = fracn an A1 - (n-1) an^2A. an(A+B) = frac an A + an B1 - an A an B
The cot(A) = 1/2, then use csc^2(A) = 1+ cot^2(A) lớn get csc(A)= pm sqrtdfrac54. Depending on increasing màn chơi of trig. Sophistication the answer is sqrtdfrac54 or pm sqrtdfrac54 ...
