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°, ⇒ Jun 21, 2020 ... Step 1: We have given, x terminates in 2nd quadrant. We have to find the value of following trig functions. Answer and Explanation: 1 ... Given: The function is f ( x ) = tan ⁡ 2 x x , x ≠ 0. ... Thus, the limit lim x → 0 ⁡ tan ⁡ 2 x x is 2 . ... Given: The function is f ( ... Solution ... So, tan2x = 12/5 when tanx = -3/2 and x terminates in quadrant IV. Like. 0. Ask a new question. Discover more ... 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. tan 2x = 2 tan x. 1−tan2 x. 4. Half Angle formulas sin2 x = 1−cos(2x). 2 cos2 x = 1+cos(2x). 2 tan2 x = 1−cos(2x). 1+cos(2x). 5. Sum to product formulas sinx+ ... May 4, 2018 ... If secθ=4, how do you use the reciprocal identity to find cosθ? How do you find the domain and range of sine, cosine, and tangent? What quadrant ...
