Exact value of cos73^(@)+cos^(2)47^(@)-sin^(2)43^(@)+sin^(2)107^(@) is equal to:

The values of cos^(2)73^(0)+cos^(2)47^(0)-sin^(2)43^(0)+sin^(2)107^(0) is equal to: ( b) (1)/(2)(c)(sqrt(3))/(2) (d) sin^(2)73^(@)+cos^(4)73^(@)

The value of cos^(2)17^(@)-sin^(2)73^(@) is:

cos ^ (2) 73 + cos ^ (2) 47-sin ^ (2) 43 + sin ^ (2107)

The value of cos^(2)17^@-sin^(2)73^@ is

sin^2 47^@+sin^2 43^@=

The value of (sin43^(@)cos47^(@)+cos43^(@)sin47^(@)) is
