Work: Calculate the value of equation 1/3*sin(15)+2*cos5-2.5-1/3*sin0-2*cos0 .
Question type: Mathematical calculation
Solution:
1/3*sin(15)+2*cos5-2.5-1/3*sin0-2*cos0
=1/3*sin15+2*cos5-2.5-1/3*sin0-2*cos0
=1/3*0.650288+2*cos5-2.5-1/3*sin0-2*cos0
=1/3*0.650288+2*0.283662-2.5-1/3*sin0-2*cos0
=1/3*0.650288+2*0.283662-2.5-1/3*0-2*cos0
=1/3*0.650288+2*0.283662-2.5-1/3*0-2*1
=0.333333*0.650288+2*0.283662-2.5-1/3*0-2*1
=0.216762+2*0.283662-2.5-1/3*0-2*1
=0.216762+0.567324-2.5-1/3*0-2*1
=0.216762+0.567324-2.5-0.333333*0-2*1
=0.216762+0.567324-2.5-0-2*1
=0.216762+0.567324-2.5-0-2
=0.784086-2.5-0-2
=-1.715914-0-2
=-1.715914-2
=-3.715914
Answer:1/3*sin(15)+2*cos5-2.5-1/3*sin0-2*cos0=-3.715914
