If anyone is able to do any of these proofs before 11am, that would be super! I've tried and tried and cannot get anything to work out... You guys are my last hope, thanks!
sin^6x + cos^6x = 1 - 3sin^2x * cos^2x
sin^2x * tan^2x + cos^2x * cot^2x = tan^2x + cot^2a - 1
(sin10x + sin6x)/(sin12x + sin4x) - (sin5x - sinx)/(sin7x + sinx) = (2sin2x)/(sin8x)
sin^6x + cos^6x = 1 - 3sin^2x * cos^2x
sin^2x * tan^2x + cos^2x * cot^2x = tan^2x + cot^2a - 1
(sin10x + sin6x)/(sin12x + sin4x) - (sin5x - sinx)/(sin7x + sinx) = (2sin2x)/(sin8x)
