In mathematics, an "identity" is an equation which is always true These can be "trivially" true, like " x = x " or usefully true, such as the Pythagorean Theorem's " a2 b2 = c2 " for right triangles There are loads of trigonometric identities, but the following are Prove the following identities sec 4 x – sec 2 x = tan 4 x tan 2 x trigonometric functions;X tan 2 x = sec 2 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

Is sec^2x-tan^2x=1 an identity
Is sec^2x-tan^2x=1 an identity- How do you verify the equation is an identity? Rearrange to get sec 2 (x) − tan 2 (x) = 1, as per the question The reason it is an identity is because it derives from an identity but is undefined when trying to divide by zero

Yes, sec 2 x−1=tan 2 x is an identity sec 2 −1=tan 2 x Let us derive the equation We know the identity sin 2 (x)cos 2 (x)=1 ——(i) Dividing throughout the equation by cos 2 (x) We get sin 2 (x)/cos 2 (x) cos 2 (x)/cos 2 (x) = 1/cos 2 (x) We know that sin 2 (x)/cos 2 (x)= tan 2 (x), and cos 2 (x)/cos 2 (x) = 1 So the equation (i) after substituting becomesHow can I prove that " 1 (sin^2x / 1 cotx) (cos^2x / 1 tanx) = sinxcosx " using trig identities?Sec^2xtan^2x= 1 1cot^2x= csc^2x cot^2x= csc^2x1 csc^2xcot^2x= 1 YOU MIGHT ALSO LIKE 8 Basic Trig Identities 8 terms kovoquiz Algebra trig identities 11 terms Start studying Trig Identities Learn vocabulary, terms, and more with flashcards, games, and other study tools Home Browse Browse Languages English French German

This is readily derived directly from the definition of the basic trigonometric functions sin and cos and Pythagoras's Theorem Confirming that the result is an identity Yes, sec2 − 1 = tan2x is an identity• Tangent tan 2x = 2 tan x/1 tan2 x = 2 cot x/ cot2 x 1 = 2/cot x – tan x tangent doubleangle identity can be accomplished by applying the same methods, instead use the sum identity for tangent, first • Note sin 2x ≠ 2 sin x;Stepbystep Solution Prove the trigonometric identity $\frac{1\tan\left(x\right)^2}{1\tan\left(x\right)^2}=\sec\left(2x\right)$
