Explanation: tan2x −cotx = 0 tan2x = cotx tan2x ⋅ tanx = 1 sin2x ⋅ sinx cos2x ⋅ cosx = 1 1 2 ⋅ (cosx − cos3x) 1 2 ⋅ (cos3 +cosx) = 1 cosx − cos3x cos3x + cosx = 1 cosx − cos3x = cos3x +cosx 2cos3x = 0
2(tanx −cotx) tan2x −cot2x = sin2x Explanation: Using the identity a2 − b2 = (a + b)(a −b), we can split the term (tan2x − cot2x) = (tanx +cotx)(tanx − cotx) and we get 2(tanx −cotx) tan2x −cot2x = 2(

shenviyash Step-by-step explanation: RHS=2 LHS=tan^2x + cot^2x = (tanx + cotx)^2+2tanx.cotx.... (a+b)^2=a^2 + b^2+2ab = (sinx÷cosx + cosx÷sinx)^2+2×1.....cause tan×cot=1 = (sin^2x+cos^2x÷cosx × sinx)^
Use the following identities: cot x = 1/tanx. and tan 2x = (2tanx)/ (1-tan 2 x) The equation then becomes (2tanx)/ (1-tan 2 x) - 1/ (tanx) = 0 Add 1/ (tanx) to each side: (2tanx)/ (1-tan 2 x) = 1/ (ta

As we know that cotx and tanx are reciprocals of each other, that is, cotx = 1/tanx, therefore we can write cot2x = 1/tan2x. From here we get the second formula of cot2x. Now, since tanx can be writte
Since the reciprocal of tan x is cot x, therefore we can write tan2x as the reciprocal of cot 2x, that is, tan2x = 1/cot2x. Let us see the tan2x formula: Tan2x Formula We can express the tan2x formula

Answer (1 of 8): My math teacher always told me to tackle the most complicated side of a trig identity first. (More complicated, by the way, usually means sums). Thus, let's look at \tan{x}+\cot{x}. T
If cot 2 x = cot (x − y) cot (x − z), then the value of cot 2 x is Q. If x is an acute angle such that both tan ( k x ) and cot ( k x ) is defined for k ∈ ( 0 , 20 ) , then which of the following is/a
