Prove that cos2x=1-tan^2x/1 tan^2x
Prove that cos2x=1-tan^2x/1 tan^2x- In this way (remembering that tanx=sinx/cosx and sin^2xcos^2x=1), the second member becomes (1sin^2x/cos^2x)/(1sin^2x/cos^2x)=((cos^2xsin^2x)/cos^2x)/((cos^2xsin^2x)/cos^2x)= =((cos^2xsin^2x)/cos^2x)*cos^2x/(cos^2xsin^2x)= =cos^2xsin^2x, that is the development of the formula of cos2xGet an answer for 'trigonometry Prove that cos2x(1 tanx*tan2x) = 1' and find homework help for other trigonometry math questions at eNotes This proves that cos 2x * (1 tan x*tan 2x) = 1

You can put this solution on YOUR website!Answer (1 of 5) Sin 2x = 2 sinx cosx Cos2x = 2 cos^2 x 1 So, (sin 2x)/(1cos 2x) = 2 sin x cos x /(1 2 cos^2 x 1) = 2 sin x cos x /2 cos^2 x = sin x /cos x = tan x For the second part,we have tanx = sin 2x/(1cos2x) Put x = 675° tan 675° = sin 135°/ 1 cos 135° Now sin 135° =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)=sinx left side = right side, therefore, equation is an identity cos^2(2x)sin^2=0 cos^2xsin^2xsin^2x
