The second limit follows from the squeeze theorem and the fact that 0 ≤ 1 − cos x x ≤ x {\displaystyle 0\leq {\frac {1-\cos x}{x}}\leq x} for x close enough to 0. This can be derived by replacing sin x in the earlier fact by 1 − cos 2 x {\textstyle {\sqrt {1-\cos ^{2}x}}} and squaring the resulting inequality.
Using the squeeze theorem, [4] we can prove that =, which is a formal restatement of the approximation for small values of θ. A more careful application of the squeeze theorem proves that lim θ → 0 tan ( θ ) θ = 1 , {\displaystyle \lim _{\theta \to 0}{\frac {\tan(\theta )}{\theta }}=1,} from which we conclude that tan ( θ ...
This is known as the squeeze theorem. [ 1 ] [ 2 ] This applies even in the cases that f ( x ) and g ( x ) take on different values at c , or are discontinuous at c . Polynomials and functions of the form x a
In the branch of mathematics known as topology, the topologist's sine curve or Warsaw sine curve is a topological space with several interesting properties that make it an important textbook example. It can be defined as the graph of the function sin(1/ x ) on the half-open interval (0, 1], together with the origin, under the topology induced ...
In either case, the value at x = 0 is defined to be the limiting value := = for all real a ≠ 0 (the limit can be proven using the squeeze theorem). The normalization causes the definite integral of the function over the real numbers to equal 1 (whereas the same integral of the unnormalized sinc function has a value of π ).
