To simplify this expression, we can first evaluate the trigonometric functions at their respective angles:
sin 30° = 1/2sin 90° = 1tg 180° = 0 (tan is undefined at 180 degrees)
Now substitute these values back into the expression:
6(1/2) - 2(1) + 3(0)= 3 - 2 + 0= 1
Therefore, the simplified expression is 1.
