Proportionality constants are written within the image sin θ, cos θ, tan θ, where θ is the common measure of five acute angles In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions) are real functions which relate an angle of a rightangled triangle to ratios of two side lengthsTrig identity $1\tan x \tan 2x = \sec 2x$ Ask Question Asked 10 years, 1 month ago Active 5 years, 11 months ago Viewed 6k times 3 0 $\begingroup$ I need to prove that $$1\tan x \tan 2x = \sec 2x$$ 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 Tan 2x identityThe Trigonometric Double Angle identities or Trig Double identities actually deals with the double angle of the trigonometric functions For instance, Sin2(α) Cos2(α) Tan2(α) Cosine2(α) Sec2(α) Cot2(α) Double Angle identities are a special case of trig identities where the double angle is obtained by adding 2 different angles In this article, we will cover
1tan^2x=sec^2x Change to sines and cosines then simplify 1tan^2x=1(sin^2x)/cos^2x =(cos^2xsin^2x)/cos^2x but cos^2xsin^2x=1 we have1tan^2x=1/cos^2x=sec^2x Trigonometry Science The correct identities are 1 tan^2x = sec^2x 1 cot^2x = csc^2x sin^2x cos^2x = 1 which correspond to B and D thank you!!!Tanx = t Sec^2 x dx= dt So now it is, 1/ (1t)^2 dt This integral is given by 1/1t and t= tanx So, it is cosx/cosx sinx tanx = t Sec^2 xPerform the addition or subtraction tanx sec^2x/tanx tan^2(x)/tan(x) sec^2x/tanx = tan^2x sec^2x / tanx then I use the identity 1tan^2u=sec^2u I Divide both side by cos^2x and we get sin^2x/cos^2x cos^2x/cos^2x = 1/cos^2x tan^2x 1 = sec^2x tan^2x = sec^2x 1 Confirming that the result is an identity
