Answer 2

Ответ:

$10$

Объяснение:

$\sin( \frac{\pi}{6} ) - 3 \cos( \frac{\pi}{3} ) + 11 \tan( \frac{\pi}{4} ) = \frac{1}{2} - 3 \times \frac{1}{2} + 11 \times 1 = \frac{1}{2} - \frac{3}{2} + 11 = - 1 + 11 = 10$

Answer 3

To simplify the expression, let's use the following trigonometric identities:

• The sine of π/6 is equal to 1/2.
• The cosine of π/3 is equal to 1/2.
• The tangent of π/4 is equal to 1.

Using these identities, we can simplify the expression:

Sin (π/6) - 3cos (π/3) + 11tg (π/4) = 1/2 - 3(1/2) + 11(1) = 1/2 - 3/2 + 11 = -2/2 + 11 = -1 + 11 = 10

Therefore, the simplified value of the expression Sin (π/6) - 3cos (π/3) + 11tg (π/4) is 10.
