Why sin(x)/x tends to 1. The following short note has appeared in a 1943 issueof the American Mathematical Monthly. The proof of the fundamental theorem. $\displaystyle\lim_{\theta\rightarrow 0}\frac{\sin\theta}{\theta}=1$. as ordinarily given in elementary books, usually depends on …

Call sinx = t, we get: f (t) = t2 +t −2 = 0. This is a quadratic equation with a +b +c = 0. One real root is ( 1) and the other is ( c a) = −2 (rejected since > 1 ). Next, solve t = sinx = 1 − → x = π 2. Answer within period ( 0,2π ): x = π 2.

(Motsvarande punkt för cosinus är x ≈ 0,73908513.) Sinusfunktionen kan representeras som ett kedjebråk Trigonometriska ettan. sin 2 ⁡ ( x ) + cos 2 ⁡ ( x ) = 1 {\displaystyle \sin ^ {2} (x)+\cos ^ {2} (x)=1} sin ⁡ ( x ) = ± 1 − cos 2 ⁡ ( x ) {\displaystyle \sin (x)=\pm {\sqrt {1-\cos ^ {2} (x)}}} cos ⁡ ( x ) = ± 1 − sin 2 ⁡ ( x ) {\displaystyle \cos (x)=\pm {\sqrt {1-\sin ^ {2} (x)}}} sin x ( 2 cos x - 1 ) Den har två faktorer, nämligen: sin x och ( 2 cos x - 1 ) Om produkten blir 0 måste någon av faktorerna vara 0 (om ingen av faktorerna är 0 kan inte produkten bli 0). Alltså kan du dela upp ekvationen sin x ( 2 cos x - 1 ) = 0 i två nya ekvationer: sin x = 0. 2 cos x - 1 = 0.

This limit says that as x gets small the ratio of sin (x) to x approaches 1. If the ratio of two numbers is close to 1, then the two numbers are about equal.

sin(x) lim = 1 x→0 x In order to compute speciﬁc formulas for the derivatives of sin(x) and cos(x), we needed to understand the behavior of sin(x)/x near x = 0 (property B). In his lecture, Professor Jerison uses the deﬁnition of sin(θ) as the y-coordinate of a point on the unit circle to prove that lim θ→0(sin(θ)/θ) = 1. Since -x is the same angle as x reflected across the x-axis, sin(-x) =-sin(x) as sin(-x) reverses it's positive and negative halves sequentially when you think of the coordinates of points on the circumference of the circle in the form p = (cos(x),sin(x)).
