Tan2x = 2tanx/ 1 tan²x What is the value of sin 225 degree?LS=3732 RS=3732 Yes, if the term at the bottom is tan^2 x, you typed tan^x, and I read it as tan x I got the proof, give me a bit of time to type it I'm sorry Mr Reiny you are right it is tan^2x LS= 2tanx/ (1tan^2x) 1/ (2cos^2x 1) = 2sinx/cosx 1/ (1sin^2x/cos^2x) 1/ (2cos^2xProduct identities function between any two functions is equal to those two functions being multiplied, eg, tan and cos multiply to sin OR for two functions opposite each other, their product is equal to one eg, tan and cot reciprocal identities can be found by going through the one, eg, sin to csc is 1/csc

The first solution is 45° more than a multiple of 180°, so (180n)° 45° should do The second solution is 30° more than a multiple of 180° and (because of the "plus / minus") also 30° less than that same multiple, so (180n)° ± 30° will cover this part(2tanx / (1 tan 2 x)) = 1 Recall Trigonometry formulas tan2A = (2tanA / (1 tan 2 A)) Substitute (2tanx / (1 tan 2 xTan(2x) as tan(xx) So tan(2x)= 2tanx/1tanxtanx We can always go for the longer approch from sinx/cosx to derive this formula

Since we know by the double angle formulae that tan2X = (2tanX)/ (1−tan^2X), we see as follows tan2 (AB) = 2tan (AB)/ (1tan^2 (AB)) Now, if we can determine what tan (AB) equals, our life would be much easier!Tap for more steps Set the first factor equal to 0 0 tan ( x) 2 = 0 tan ( x) − 2 = 0 Add 2 2 to both sides of the equation tan ( x) = 2 tan ( x) = 2 Take the inverse tangent of both sides of the equation to extract x x from inside the tangent x = arctan ( 2)Sin(2X) = 2 sinX cosX cos(2X) = 1 2sin 2 X = 2cos 2 X 1 tan(2X) = 2tanX / 1 tan 2 X Multiple Angle Formulas sin(3X) = 3sinX 4sin 3 X cos(3X) = 4cos 3 X 3cosX sin(4X) = 4sinXcosX 8sin 3 XcosX cos(4X) = 8cos 4 X 8cos 2 X 1 Half Angle Formulas
If(2tanx/(1tan^2x))=1, then x can equal? Tan2x=2tanx/1tan^2x Stepbystep explanation Tan 2x is the trigonometric formulas which are called as double angle formulas because they have double angles in their trigonometric functionsYou get these gems as you gain rep from other members for making good contributions and giving helpful advice nope, the simple way is to rewrite tan2x as sin2x/cos2x then integrate by substitution I get the answer as 1/2 ln (cos2x) c

I understand the trig function involved if it's just (2x) and tan is not squared @Tyrion101, despite what others have said in this thread, yes, tan 2 ( 2 x) is the square of tan ( 2 x) Tyrion101 said But is it equal to (2tanx/1tan^2x)^2 is what I'm asking I may have been unclear But, since the cosine is always less than or equal to 2, we see that the statement tex\cos(2x)=2/tex cannot have any solutions at all (that is, whatever number "x" you substitute into the expression on the lefthand side, will never make cos(2x) equal to 2 8 \frac{2 tan ~x}{1tan^2 x} =\frac{1}{\sqrt{3} } \\tan ~2x=tan~30,tan~210,tan~ (),tan~()\\2x=30,210,390,570\\x=15^\circ,105^\circ,195^\circ,285^\circ zaniahsims zaniahsims Answer
