Identities expressing trig functions in terms of their supplements Sum, difference, and double angle formulas for tangent The half angle formulas The ones for sine and cosine take the positive or negative square root depending on the quadrant of the angle θ/2 For example, if θ/2 is an acute angle, then the positive root would be used1803 · sin 2 ( 3 x 4 − 5 x 2 87) cos 2 ( 3 x 4 − 5 x 2 87) = 1 sin 2 ( 3 x 4 − 5 x 2 87) cos 2 ( 3 x 4 − 5 x 2 87) = 1 tan2(θ)1 = tan 2 ( θ) 1 = Show Solution tan 2 ( θ) 1 = sec 2 ( θ) tan 2 ( θ) 1 = sec 2 ( θ) If you know the formula from Problem 1 inCosec(2nπ θ) = cosecθ;

Tan ⁡ ( α − β) = tan ⁡ ( α) − tan ⁡ ( β) 1 tan ⁡ ( α) tan ⁡ ( β) \tan (\alpha \beta) = \dfrac {\tan (\alpha) \tan (\beta)} {1 \tan (\alpha) \tan (\beta)} tan(α−β)= 1tan(α)tan(β)tan(α)−tan(β) By the way, in the above identities, the angles are denoted by Greek lettersLHS = 1 sin ⁡ θ cos ⁡ θ = ( 1 sin ⁡ θ) cos ⁡ θ) × ( 1 − sin ⁡ θ) 1 − sin ⁡ θ = 1 − sin 2 ⁡ θ cos ⁡ θ ( 1 − sin ⁡ θ) = cos 2 ⁡ θ cos ⁡ θ ( 1 − sin ⁡ θ) = cos ⁡ θ ( 1 − sin ⁡ θ) = RHS Restrictions undefined where cos ⁡ θ = 0, sin ⁡ θ = 1 and where tan ⁡ θ is undefined Therefore θ ≠ 90 °;0117 · Trigonometric equations can be solved using the algebraic methods and trigonometric identities and values discussed in earlier sections Solve the equation 2 cos θ − 1 = 0 for 0 ≤ (tan 2 theta)`, so we have `tan 2 theta1/(tan 2 theta)=0` `tan^2 2θ = 1`

Cos(2nπ θ) = cosθ;Cos 2 ⁡ θ sin 2 ⁡ θ = 1 {\displaystyle \cos ^ {2}\theta \sin ^ {2}\theta =1} The other trigonometric functions can be found along the unit circle as tan ⁡ θ = y B {\displaystyle \tan \theta =y_ {\mathrm {B} }\quad } and cot ⁡ θ = x C , {\displaystyle \quad \cot \theta =x_ {\mathrm {C} },}All the trigonometric identities on one page Color coded Mobile friendly With PDF and JPG downloads
