Question

Cos² 8° + sin² 8° + 1

Answer 1

Ответ:

cos²8° + sin²8° +1 = 1 + 1 = 2

Answer 2

To find the value of the expression cos² 8° + sin² 8° + 1, we can use the trigonometric identity:

cos² θ + sin² θ = 1

Substituting θ = 8° into the identity, we get:

cos² 8° + sin² 8° = 1

Therefore, the value of the expression cos² 8° + sin² 8° + 1 is:

1 + 1 = 2
