WebbNow, we have a trigonometric identity 1 + tan^2x = sec^2x which implies tan^2x = sec^2x - 1. Since tan x can be expressed as the ratio of sine function and cosine function, ... So, the domain of tan 2x is R - {(2n + 1)π/4, n ∈ Z}. The range of tan2x is all real numbers, that is, R. How to Find the Derivative of Tan2x? Webb30 okt. 2014 · sec ( x) = 1 c o s ( x) and − 1 ≤ c o s ( x) ≤ 1 so the equation has no roots. There are none of those either. Basically no roots. Since cos ( z) = e i z + e − i z 2 has no poles, 1 cos ( z) has no zeroes. Since we want 1 / c o s 2 ( x) = 0 therefore c o s 2 ( x) must → infinity, but because c o s ( x) ≤ 1 hence we have no roots.
