Work: Calculate the value of equation -2*sin38.4+2*cos38.4-sin19.2 .
Question type: Mathematical calculation
Solution:
-2*sin38.4+2*cos38.4-sin19.2
=-2*0.644897+2*cos38.4-sin19.2
=-2*0.644897+2*0.76427-sin19.2
=-2*0.644897+2*0.76427-0.343315
=-1.289794+2*0.76427-0.343315
=-1.289794+1.52854-0.343315
=0.238746-0.343315
=-0.104569
Answer:-2*sin38.4+2*cos38.4-sin19.2=-0.104569
