2sin ^ (2) (8 (1 ^ (@)) / (2)) + 4cos16 ^ (@) sin (7 (1 ^ (@)) / (2)) sin (8 (1 ^ (@)) / (2)) + cos32 ^ (@) =

(cos^(2)1^(0)-cos^(2)2^(0))/(2sin3^(0)*sin1^(0)) is equal to

The value of the expression (2(sin1^(0)+sin2^(0)+sin3^(0)+...+sin89^(@)))/(2(cos1^(0)+cos2^(0)+...+cos44^(0))+1) equals

The value of expression (2(sin1^(0)+sin2^(0)+sin3^(0)+...+sin89^(@)))/(2(cos1^(0)+cos2^(0)++cos44^(0))+1) (a) sqrt(2)(b)(1)/(sqrt(2))(c)(1)/(2)(d)0

" The value of "(sin1^(0)+sin3^(0)+sin5^(0)+sin7^(0))/(cos1^(0)*cos2^(0)*sin4^(0))" is "

Prove that: (cos8^(0)+sin8^(0))/(cos8^(0)-sin8^(@))=tan37^(0)

(cos20^(0)+8sin70^(0)sin50^(@)sin10^(0))/(sin^(2)80^(@)) is equal to

sin ^ (2) 48 ^ (0) -cos ^ (2) 12 ^ (0) = - (sqrt (5 + 1)) / (8)
