Work: Calculate the value of equation 82^2-4*128^2*(sin(3.1415/27.170500))^2 .
Question type: Mathematical calculation
Solution:
82^2-4*128^2*(sin(3.1415/27.170500))^2
=82^2-4*128^2*(sin0.115622)^2
=82^2-4*128^2*0.115365^2
=6724-4*128^2*0.115365^2
=6724-4*16384*0.115365^2
=6724-4*16384*0.013309083225
=6724-65536*0.013309083225
=6724-872.224078
=5851.775922
Answer:82^2-4*128^2*(sin(3.1415/27.170500))^2=5851.775922
