Oct 3, 2016 0 Explanation: 1 − cosx = 2sin2( x 2) so 1 − cosx x = ( x 4)( sin( x 2) x 2)2 then lim x→0 1 −cosx x ≡ lim x→0 ( x 4)( sin( x 2) x 2)2 = 0 ⋅ 1 = 0 Answer link Jim H Oct 3, 2016

Nettet2. okt. 2024 · If you start with − 1 ≤ cos(1 x) ≤ 1 and multiply through by sin(x), you actually need to make sure that sin(x) > 0 in order to preserve the direction of the inequalities. For example, the inequality you wrote down is not true for x = − π / 4, say. So there are actually two cases: x → 0 − and x → 0 +. The spirit is correct though! – Ehsaan NettetGiải các bài toán của bạn sử dụng công cụ giải toán miễn phí của chúng tôi với lời giải theo từng bước.
