Answer 1

Ответ:

5/2

Объяснение:

3*1+0-1/2

3+0-1/2

5/2

Answer 2

To simplify the expression 3sin(π/2) + cos(π/2) - sin(π/6), you can use the values of sine and cosine for these specific angles:

1. sin(π/2) = 1
2. cos(π/2) = 0
3. sin(π/6) = 0.5

Now, substitute these values into the expression:

3(1) + 0 - 0.5

Now, calculate the expression:

3 - 0.5 = 2.5

So, 3sin(π/2) + cos(π/2) - sin(π/6) simplifies to 2.5.
