How to simplify sin 3x
WebThe process is somewhat confusing to find the exact value, but here it is: Let x = 18° (therefore 5x = 90°) sin (3x) = cos (90° - 3x) = cos (5x - 3x) = cos (2x) sin (3x) = cos (2x) (Remember that x = 18°, so that is why this is true.) 3sin (x) - 4sin^3 (x) = 1 - 2sin^2 (x) (I expanded these.) Let y = sin (x) 4y^3 - 2y^2 - 3y + 1 = 0 http://mathcentral.uregina.ca/QQ/database/QQ.09.02/michael6.html
