[1/1 Formula]
Work: Calculate the value of equation sin(72)+2/3*cos(72*1.5) .
Question type: Mathematical calculation
Solution:
sin(72)+2/3*cos(72*1.5)
=sin72+2/3*cos(72*1.5)
=sin72+2/3*cos108
=0.253823+2/3*cos108
=0.253823+2/3*0.37551
=0.253823+0.666667*0.37551
=0.253823+0.25034
=0.504163
Answer:sin(72)+2/3*cos(72*1.5)=0.504163
Note: Radian
