Example limit of start fraction sine of x divided by sine of 2 x end fraction as x approaches 0 can be rewritten as the limit of start fraction 1 divided by 2 cosine of x end fraction as x approaches 0, using a trig identity. Using options E through G, try evaluating the limit in its new form, circling back to A, direct substitution.
Toprove that \displaystyle\lim_ {x\to 0}\dfrac {x} {\text {sin} (x)}=1 x→0lim sin(x)x = 1, we can use the squeeze theorem. Luke suggested that we use the functions \goldD {g (x)=x+1} g(x) = x + 1 and \maroonD {h (x)=-x+1} h(x) = −x + 1 in order to apply the squeeze theorem. \small {1} 1 \small {2} 2 \small {\llap {-}2} -2 \small {1} 1
Yes by definition cot x = 1 tan x, and tan x = sin x cos x, so. cot x = 1 sin x / cos x = cos x sin x. Thus, squaring both sides of the equation, we obtain cot 2 x = cos 2 x sin 2 x. Share. Cite. Follow. answered Feb 11, 2019 at 22:09. DanLewis3264. 2,340 12 22.
