Work: Calculate the value of equation -2*sin38.3+2*cos38.3-sin19.15 .
Question type: Mathematical calculation
Solution:
-2*sin38.3+2*cos38.3-sin19.15
=-2*0.565375+2*cos38.3-sin19.15
=-2*0.565375+2*0.824834-sin19.15
=-2*0.565375+2*0.824834-0.295944
=-1.13075+2*0.824834-0.295944
=-1.13075+1.649668-0.295944
=0.518918-0.295944
=0.222974
Answer:-2*sin38.3+2*cos38.3-sin19.15=0.222974
