F f x secx then limx→π3f x −f π3 x−π3 is
WebYou can prove the sec x and cosec x derivatives using a combination of the power rule and the chain rule (which you will learn later). Essentially what the chain rule says is that. d/dx (f (g (x)) = d/dg (x) (f (g (x)) * d/dx (g (x)) When you have sec x = (cos x)^-1 or cosec x = (sin x)^-1, you have it in the form f (g (x)) where f (x) = x^-1 ... Webx→a f (x) g(x) in the case that both f (a) = 0 and g(a) = 0. I These limits are called indeterminate and denoted as 0 0. Theorem If functions f ,g : I → R are differentiable in an open interval containing x = a, with f (a) = g(a) = 0 and g0(x) 6= 0 for x ∈ I −{a}, then holds lim x→a f (x) g(x) = lim x→a f 0(x) g0(x),
