Decide whether the equation is a trigonometric identity explain your reasoning cos^2x(1tan^2x)=1 secxtanx(1sin^2x)=sinx cos^2(2x)sin^2=0 ** cos^2x(1tan^2x)=1 cos^2xsin^2x/cos^2x=1 cos^2xsin^2x=1 left side = right side, therefore, equation is an identity secxtanx(1sin^2x)=sinx (1/cosx*sinx/cosx)(11cos^2x (sinx/cos^2x)(cos^2x)=sinx2 x I started this by making sec 1/cos and using the double angle identity for that and it didn't work at all in any way ever Not sure why I can't do that, but something was wrong Anyways I looked at the solutions manual and they magic out 1 tan x tan 2 x = 1 tanThe Pythagorean Identities Cool Math has free online cool math lessons, cool math games and fun math activities Really clear math lessons (prealgebra, algebra, precalculus), cool math games, online graphing calculators, geometry art, fractals, polyhedra, parents and teachers areas too
