Question 633991: Prove: cot30° sin30° cos30° = 1-sinē30°
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
cot(30)*sin(30)*cos(30) = 1-sin^2(30)
(cos(30)/sin(30))*sin(30)*cos(30) = 1-sin^2(30)
cos(30)*cos(30) = 1-sin^2(30)
cos^2(30) = 1-sin^2(30)
1-sin^2(30) = 1-sin^2(30)
So the identity has been verified.
