Answer:
[(2 + √3)/4] = 0.9330127
Step-by-step explanation:
We know that
cos (pi/12) ^ 2 =
cos (pi/12)* cos (pi/12) =
[(√6 + √2)/4]*[(√6 + √2)/4] =
(0.9659)*(0.9659) = 0.9330127
[(2 + √3)/4] = 0.9330127

Answer:
f(7) = 2
Step-by-step explanation:
3f(7) + f(7)g(7) = 18
3f(7) + f(7)(6) = 18
f(7) (3 + 6) = 18
f(7) x (9) = 18
f(7) = 2
