How do you write cot(X) as 1 tan(x)?
If we write cot(x) as 1 tan(x), we get: cot(x) +tan(x) = 1 tan(x) + tan(x) Then we bring under a common denominator: = 1 tan(x) + tan(x) ⋅ tan(x) tan(x) = 1 + tan2(x) tan(x)
What is the Rat of Tan^4x + cot^4 x?
Let us take a RAT of 1–1–sqrt 2, where tan x = 1, then cot x = 1. Let us take a RAT of 3–4–5, where tan x = 3/4, then cot x = 4/3. So tan^4 x + cot^4 x = (3/4)^4+ (4/3)^4 = 0.31640625 + 3.160493827 = 3.476900077.
How to treat Tanx and cotx separately?
Treat the tanx separately and the cotx separately. Don't forget the derivatives for trig functions: Derivative of tanx is sec2x. Derivative of cotx is −csc2x. Since they are adding together, we can treat them it as tan'x and cot'(x): A bit of a different approach... Rewrite in terms of sine and cosine. Now use the chain rule to differentiate.

secx ‚ 1 or secx • ¡1: The period of secx is precisely the same as that of cosx, which means that the period of secx is 2…. The function secx is an even function, and this is because cosx is an even function. Finally, at every value of x not in the domain of secx, the function has both left and right vertical asymptotes. If a =:::;¡3 ...
