3 = tan 2x sin(2x + (π/3)) sin(2x + (2π/3)) cos(2x + (π/3)) cos(2x + (2π/3)). = tan 2x cos(π/3) − cos(4x + π) cos(π/3) + cos(4x + π). = tan 2x. 1 + 2 cos 4x. 1 ... 2sec 2 x – tan 2 x = 5 ⇒ 2tan 2 x + 2 – tan 2 x = 5 ⇒ tan 2 x = 3 ⇒ tanx = √3 Given, 0° ≤ x ≤ 90°, ⇒ Oct 18, 2015 ... My question is this, using the identity: e^(ix)=cos(x)+jsin(x) show that tan(2x)=−i(e^(4ix)−1)/(e^(4ix)+1) Apr 24, 2022 ... Tan2x is a double angle identity. Because the tangent function is a ratio of the sine and cosine functions, it may also be represented as tan2x = sin 2x/cos 2x. y = arctan(tan2x)). Natural Language; Math Input.
