Decimal expansion of the least x>0 satisfying 1/(1+x^2)=6*cos(x). 6. 1, 5, 2, 0, 4, 4, 9, 4, 5, 0, 8, 3, 3, 8, 1, 6, 3, 6, 3, 1, 4, 7, 4, 5, 8, 8, 2, 0, 8, ... Mar 29, 2022 ... We evaluate the limit of 1-cosx / x as x goes to 0. This is a fundamental limit you're expected to know, so let's see where it comes from! What is the Maclaurin series of COSX? The Maclaurin series of cos(x) is the same as the Taylor series centered at 0, which can be written as 1 - ... The linear approximation of cos x near x0 = 0 approximates the graph of the cosine function by the straight horizontal line y = 1. This doesn't look like a very ... [0,π]. f′(x) = − sin x − 2 sin x cos x f′(x)=0=⇒ − sin x − 2 sin x cos x =0=⇒ − sin x(1 + 2 cos) = 0. =⇒ sin x =0=⇒ x = 0, π. or. =⇒ 1 + 2 cos x =0=⇒ cos x = −.
