True Start with the well known pythagorean identity sin^2x cos^2x = 1 This is readily derived directly from the definition of the basic trigonometric functions sin and cos and Pythagoras's Theorem 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 identityTo determine the difference identity for tangent, use the fact that tan(−β) = −tanβ Example 1 Find the exact value of tan 75° Because 75° = 45° 30° Example 2 Verify that tan (180° − x) = −tan x Example 3 Verify that tan (180° x) = tan x Example 4 Verify that tan (360° − x) = − tan x The preceding three examples verify three formulas known as the reductionTrigonometric Identities Worksheet I Prove each identity 1) tanxcos x = sinx 2) cotxsec x = esc x 3) sin x cot x == cos x 4) tan xcsc x sec

Purplemath 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 "a 2 b 2 = c 2" for right trianglesThere are loads of trigonometric identities, but the following are the ones you're most likely to see and useTrig identities or a trig substitution mcTYintusingtrig091 Some integrals involving trigonometric functions can be evaluated by using the trigonometric identities and using the identity 1tan2 θ = sec2 θ this reduces to 1 a Z 1dθ = 1 a θ c = 1 a tan−1 x a cTo integrate tan^22x, also written as ∫tan 2 2x dx, tan squared 2x, (tan2x)^2, and tan^2(2x), we start by utilising standard trig identities to change the form of the integral Our goal is to have sec 2 2x in the new form because there is a standard integration solution for that in formula booklets that we can use We recall the Pythagorean trig identity, and multiply the angles by 2

The tan squared function rule is also popularly expressed in two forms in trigonometry $\tan^2{x} \,=\, \sec^2{x}1$ $\tan^2{A} \,=\, \sec^2{A}1$ In this way, you can write the square of tangent function formula in terms of any angle in mathematics Proof Take, the theta is an angle of a right triangle, then the tangent and secant areLet's start with the left side since it has more going on Using basic trig identities, we know tan (θ) can be converted to sin (θ)/ cos (θ), which makes everything sines and cosines 1 − c o s ( 2 θ) = ( s i n ( θ) c o s ( θ) ) s i n ( 2 θ) Distribute the right side of the equation 1 − c o s ( 2 θ) = 2 s i n 2 ( θ)2 tan sec sin 1 tan x x x x Microsoft Word trigonometric_identities_with_solutionsdoc Author TrifonMadas Created Date 6/3/15 PM

In this video I go over a quick proof of the trigonometric identities tan(x y) and tan(x – y) The identity is simple to derive because we can use the iden2 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 tanTan is an "odd" identity quotient identity (for tangent) algebra/ simplify 1) 2) cos tan (x) Strategy 1) get rid of the negatives 2) üy to change terms to sin's and COS's 3) simplFy • tan (x) tan x sm x cos x smx cos (x) cosx • cosx • Prove Strategy
