(1 + tan 2 x) cos x = sec x
(1 + tan 2 x) cos x = sec x-The first thing that comes to my mind is I want everything in terms of sin's and cos's if I can, so let's multiply through by cosx so that we can at least get rid of that secx=1cosx term ( tan 2 x sec x) cos x = 1 − cos 2 x Now that 1 − cos 2 x is popping out at me because I remember the Pythagorean identity sin 2 x cos 2 x = 1Find sin 2x, cos 2x, tan 2x if secx = 135,π2

IF you recognize (from the fundamental identities) that sec^2 x 1 = tan^2 x, then working with the righthand side should be obvious Multply numerator and denominator of the righthand side by (sec x 1) cos x(sec x 1)(sec x 1)(sec x 1) cos x(sec x 1)sec^2 x 1 cos x(sec x 1)xxx tan^2 x OKnow we have the denominator we want1 Answer Monzur R We have to use the common identity sin2x cos2x = 1 Dividing each term by cos2x, we get tan2x 1 = sec2x So cosx(tan2x 1) = cos(sec2x) = cosx 1 cos2x = 1 cosx = secx Answer linkProve (cosx) (1tanx)^2 = secx2sinx full pad » x^2 x^ {\msquare} \log_ {\msquare} \sqrt {\square} \nthroot \msquare {\square} \le \ge
