3sin(0°) = 3(0) = 0cos(60°) = 0.5tg(30°) = 1/√3sin(90°) = 1
Putting these values back into the expression:3(0) + 0.5 + 1/√3 - 1= 0 + 0.5 + 1/√3 - 1= 0.5 + 1/√3 - 1= 0.5 + 0.577 - 1= 1.077 - 1= 0.077
Therefore, the value of the expression is 0.077.
3sin(0°) = 3(0) = 0
cos(60°) = 0.5
tg(30°) = 1/√3
sin(90°) = 1
Putting these values back into the expression:
3(0) + 0.5 + 1/√3 - 1
= 0 + 0.5 + 1/√3 - 1
= 0.5 + 1/√3 - 1
= 0.5 + 0.577 - 1
= 1.077 - 1
= 0.077
Therefore, the value of the expression is 0.077.
