Lim of cosx/x

Nettet13. mar. 2024 · 具体来说，我们可以考虑比较函数f(x) = cos(x)/x和一个已知的发散的函数g(x) = 1/x，当x趋近于无穷大时，两个函数的极限都等于零，即： lim x->∞ f(x)/g(x) = lim x->∞ x*cos(x) = ∞ 因此，根据极限比较测试法，如果一个函数在某一点x0处与一个发散的函数g(x)的比值趋近于无穷大，则该函数的反常积分也会在 ... Nettet2. sep. 2024 · September 2, 2024 Calculus / Mathematics We will prove that the limit of ( cos ( x) – 1) / x as x approaches 0 is equal to 0. We will prove that in two different ways. Proof. We would like to prove the next limit: lim x → 0 cos ( x) – 1 x = 0 We do have the next identity: cos ( x) = 1 – 2 sin 2 ( x / 2) Therefore, we get

L'idée est que l'on peut encadrer par deux constantes (lesquelles ?) puis en déduire un encadrement de par deux fonctions qui tendent vers 0 à l'infini. m3m iconic tower https://designchristelle.com
