WebJul 26, 2015 · Using first principle, the derivative of any function f(x) is given as d(f(x)) dx = lim h → 0f(x + h) − f(x) h Hence, derivative of tan2x is given as d(tan2x) dx = lim h → 0tan2(x + h) − tan2(x) h = lim h → 0(tan(x + h) − tan(x))(tan(x + h) + tan(x)) h = lim h → 0tan(x + h) − tan(x) h × lim h → 0(tan(x + h) + tan(x)) = lim h → 0 sin ( x + h) cos … Webtanx = sinx/cosx cotx = 1/tanx = cosx/sinx secx = 1/cosx cscx. = 1/sinx As you can see, if secx= 1/cosx, then sec²x= (1/cosx)² = 1/cos²x, similarly, -csc²x = - 1/sin²x They are equivalent, either is fine. It's personal preference but depends on …

We start with the function f (0)(x) = f (x) = tanx Then, we compute the first few derivatives: = sec2(x) f (2)(x) = (2sec2x)(secxtanx)() = 2sec2xtanx = 2(1 + tan2x)tanx WebTo find the integration of tan x, with respect to x, we express tan x in terms of sine and cosine so that it becomes an integrable function. As per the definition of tan x, we have tan x = sin x / cos x. ∫ tan x =∫ (sin x /cos x) .dx. This can be rewritten as ∫ 1 cosx ∫ 1 cos x. sin x. dx. Let us find the indefinite integral of tan x ...
