Work: Calculate the value of equation π/2+(π/2)*sin(π/2)-π*sin(π/4)-π/2+2*cos(π/2) .
Question type: Mathematical calculation
Solution:
π/2+(π/2)*sin(π/2)-π*sin(π/4)-π/2+2*cos(π/2)
=π/2+1.570796*sin(π/2)-π*sin(π/4)-π/2+2*cos(π/2)
=π/2+1.570796*sin1.570796-π*sin(π/4)-π/2+2*cos(π/2)
=π/2+1.570796*sin1.570796-π*sin0.785398-π/2+2*cos(π/2)
=π/2+1.570796*sin1.570796-π*sin0.785398-π/2+2*cos1.570796
=π/2+1.570796*1-π*sin0.785398-π/2+2*cos1.570796
=π/2+1.570796*1-π*0.707107-π/2+2*cos1.570796
=π/2+1.570796*1-π*0.707107-π/2+2*0
=1.570796+1.570796*1-π*0.707107-π/2+2*0
=1.570796+1.570796-π*0.707107-π/2+2*0
=1.570796+1.570796-2.221442-π/2+2*0
=1.570796+1.570796-2.221442-1.570796+2*0
=1.570796+1.570796-2.221442-1.570796+0
=3.141592-2.221442-1.570796+0
=0.92015-1.570796+0
=-0.650646+0
=-0.650646
Answer:π/2+(π/2)*sin(π/2)-π*sin(π/4)-π/2+2*cos(π/2)=-0.650646
