Answer 2

To simplify the expression, let's start by evaluating each trigonometric function:

1. cos(π/3) = 1/2 (cosine of 60 degrees)
2. sin(-π/6) = -1/2 (sine of -30 degrees)

Now, plug these values back into the expression:

6cos(π/3) - 2sin(-π/6) = 6 * (1/2) - 2 * (-1/2)

Now, simplify further:

6 * (1/2) = 3 2 * (-1/2) = -1

So, the final result is:

6cos(π/3) - 2sin(-π/6) = 3 - (-1) = 3 + 1 = 4
