To simplify the given expression, we can break it down step by step:

2sinП - 2cos3П/2 + 3tgП/4 - ctgП/2Simplify each trigonometric function:
sin П = sin(2π + П) = sinПcos(3π/2) = -cos(π/2) = 0tg(П/4) = 1ctg(П/2) = cot(П/2) = 0Substitute the simplified values:
2sinП - 2(0) + 3(1) - 0Simplify further:
2sinП + 3Therefore, the simplified expression is:
2sinП + 3
