Question

Sin 71 cos 11-soc 71 sin11​

Answer 1

Ответ:

$\frac{ \sqrt{3} }{2}$

Объяснение:

$\sin(71) \cos(11) - \cos(71) \sin(11) = \sin(71 - 11) = \sin(60) = \frac{ \sqrt{3} }{2}$

Answer 2

Ответ:

Sin(71-11)

Sin(60)

Answer 3

It seems like you want to evaluate the expression:

sin(71) * cos(11) - cos(71) * sin(11)

Let's calculate it step by step:

1. Calculate sin(71) and cos(71): sin(71) ≈ 0.9511 cos(71) ≈ 0.3090

2. Calculate sin(11) and cos(11): sin(11) ≈ 0.1908 cos(11) ≈ 0.9816

3. Now, plug these values into the expression: 0.9511 * 0.9816 - 0.3090 * 0.1908

4. Perform the multiplications: ≈ 0.9331 - 0.0589

5. Finally, subtract the two results: ≈ 0.8742

So, sin(71) * cos(11) - cos(71) * sin(11) is approximately equal to 0.8742.
