sin(pi) = 02cos(pi/3) = 2 * 0.5 = 1tan(45°) = 11/3 = 1/3ctg(30°) = 1/√3
Therefore, the expression simplifies to:0 + 1 - 1 + 1/3 √3 = 1 - 1 + 1/3 √3 = 1/3√3
sin(pi) = 0
2cos(pi/3) = 2 * 0.5 = 1
tan(45°) = 1
1/3 = 1/3
ctg(30°) = 1/√3
Therefore, the expression simplifies to:
0 + 1 - 1 + 1/3 √3 = 1 - 1 + 1/3 √3 = 1/3√3
