First, let's simplify each term separately:
sin(0) = 0 (sin of 0 degrees is 0)
cos(180) = -1 (cos of 180 degrees is -1)
2tg(0) = 2 tan(0) = 2 0 = 0 (tan of 0 degrees is 0)
3sin(90) = 3 (sin of 90 degrees is 1, multiplied by 3 is 3)
Now, let's substitute these values back into the equation:
0 + (-1) - 0 + 3 = -1 + 3 = 2
So, sin 0 + cos 180 - 2tg 0 + 3 sin 90 equals 2.
