Work: Calculate the value of equation 82^2*10^2-4*128.6718576257230*10^2*(sin(3.1415926536/10))^2 .
Question type: Mathematical calculation
Solution:
82^2*10^2-4*128.6718576257230*10^2*(sin(3.1415926536/10))^2
=82^2*10^2-4*128.6718576257230*10^2*(sin0.314159)^2
=82^2*10^2-4*128.6718576257230*10^2*0.309017^2
=6724*10^2-4*128.671857625723*10^2*0.309017^2
=6724*100-4*128.671857625723*10^2*0.309017^2
=6724*100-4*128.671857625723*100*0.309017^2
=6724*100-4*128.671857625723*100*0.095491506289
=672400-4*128.671857625723*100*0.095491506289
=672400-514.687431*100*0.095491506289
=672400-51468.7431*0.095491506289
=672400-4914.827805
=667485.172195
Answer:82^2*10^2-4*128.6718576257230*10^2*(sin(3.1415926536/10))^2=667485.172195
