For instance, Sin 2X, Cos 2Y, Tan 2X, Sin 3X Thus, here we denote further various formulas for multiple angles Sin2X= 2SinX CosX= 2Tan X/1 Tan 2X;$\begingroup$ Well, if your instructor insisted that you do this by calling in the doubleangle formula, then I would replace my second paragraph with a criticism of the instructor for making things unnecessarily difficult Indeed, if the question had been to solve $\tan(9x/2)=1$, it would have been frustratingly difficult to use the ninefold angle formula and the halfangle formulas, i changed the tan2x into 2tanx/1tan^2 x then divided both sides by 2tanx but kinda ended up with tan^2 x=2 help P pLuvia Guest Use the double angle formula crap 3(2tanx)/(1tan^2x)=tanx Move the bottom thingo on the LHS to the RHSand u end up with something like this 6tanx=tanx (1tan^2x) u expand it

2tanx/1 tan^2x formula

2tanx/1 tan^2x formula-Is not valid for x = 90°k180° and for tanx = ±1 so you have to test these values in the given equation The equation 3\tan^3 x \tan x = 0 factors as \tan x (\color {red} {3}\tan^2 x 1) = 0 (you forgot the 3) Hence, \tan x = 0 or \tan x = \pm \dfrac {1} {\sqrt {3}} Both of these should be easyTransformational Formula Here, we have two sets of transformational Formula

 2tanx = 3 tan^2x tan^2x 2tanx 3 = 0 (tanx 3) (tanx 1) = 0 tanx = 3 or tanx = 1 if tanx = 3, x must be in II or IV by the CAST rule x = 1084° or 24° if x = 1, then x must be in I or III x = 45° or x = 225° 👍Tan2x=2tanx/1tan^2x Given this circumstance, what is the formula of trigonometry?Tan2x = 2tanx/(1tan 2 x) From this making tan 2 x the subject;

We will use the following trigonometric formula to prove the formula for tan 2x tan (a b) = (tan a tan b)/ (1 tan a tan b) We have tan 2x = tan (x x) = (tan x tan x)/ (1 tan x tan x) = 2 tan x/ (1 tan 2 x) Hence, we have derived the tan 2x formula using the angle sum formula of the tangent function1 tan^2x = sec^2x 1 Cot^2x = csc^2x tanx sinx/cosx cotx cosx/sinx Double Angle Formula see graph sin2x 2sinxcosx cos2x (1) cos^2xsin^2x cos2x (2) cos 2cos^21 cos2x (3) sin 1 sin^2x tan2x 2tanx/1tan^2x half angle formula see graphic The sign is determined by the quadrant in which the angle lies after being divided byTrigonometry Solve for x tan (2x)= (2tan (x))/ (1tan (x)^2) tan(2x) = 2tan(x) 1−tan2 (x) tan ( 2 x) = 2 tan ( x) 1 tan 2 ( x) Since x x is on the right side of the equation, switch the sides so it is on the left side of the equation 2tan(x) 1− tan2(x) = tan(2x) 2 tan ( x) 1 tan 2 ( x) = tan ( 2 x)

 (It's a consequence of the Pythagorean theorem) There are other variants too, like tan²(x) 1 = sec²(x) when you divide both sides by cos²(x) Taking into account what is the formula for Tan2x? tan 2x = 2tanx/(1tan^2(x)) I actually should have used tformula But it is dragging me down when I write the one up here It is just a tedious work Just remember, when you substitue the tformula, always let t = tanx/2 (where x is the one that you are trying toFirst simply it by using tan2x formula Tan2x=2tanx/ (1tan^2 (x)) Then change it into sinx and Cosx In denominator you will get cos^2 (x)sin^2 (x) that is equal to cos (2x) In numerator you will get 2cos^2 (x) That is equal to 1cos2x It becomes (1cos2x)/cos2x =>sec2x 1 dsec2x /dx=2sec2xtan2x
