Answer 3

It looks like you've written a mathematical expression involving trigonometric functions. Let's break it down step by step:

1. sin(π/2) = 1 (sine of π/2 is 1)
2. cos(π/2) = 0 (cosine of π/2 is 0)
3. sin(π/6) = 0.5 (sine of π/6 is 0.5)

Now, substitute these values into your expression:

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

Simplify the expression:

3 + 0 - 0.5 = 2.5

So, the value of the expression 3sin(π/2) + cos(π/2) - sin(π/6) is 2.5.
