Diese Frage ist relativ leicht zu beantworten: x0 ist immer 1. Als Begründung benutzen wir die Potenzgesetze der Division: x1. 3 geteilt durch x oder 2 minus x geteilt durch x plus 2 oder irgendetwas anderes wie zum Beispiel 4 durch Eistüte plus 1 sind Bruchterme. Keine Bruchterme wären. \ll(1)(x^2/(x-1))/x \ll(2)x/(x-1) \ll(3)1/(x-1)+1 \ll(4)x^2/(x-1)-x Ich habe die Schritte nummeriert, damit man es besser erkennen kann (die Terme.

Hence X cannot be 0 or 1. A square matrix has an inverse if and only if its determinant has an inverse in the coefficient ring. Thus, the two distinct notions of the inverse of a function are strongly related in this case, while they must be carefully distinguished in the general case as noted above.

The trigonometric functions are related by the reciprocal identity: the cotangent is the reciprocal of the tangent; the secant is the reciprocal of the cosine; the cosecant is the reciprocal of the sine.

A ring in which every nonzero element has a multiplicative inverse is a division ring ; likewise an algebra in which this holds is a division algebra.

The reciprocal may be computed by hand with the use of long division. This continues until the desired precision is reached.

A typical initial guess can be found by rounding b to a nearby power of 2, then using bit shifts to compute its reciprocal. In terms of the approximation algorithm described above, this is needed to prove that the change in y will eventually become arbitrarily small.

This iteration can also be generalized to a wider sort of inverses; for example, matrix inverses. Every real or complex number excluding zero has a reciprocal, and reciprocals of certain irrational numbers can have important special properties.

Such irrational numbers share an evident property: they have the same fractional part as their reciprocal, since these numbers differ by an integer.

In the absence of associativity, the sedenions provide a counterexample. The converse does not hold: an element which is not a zero divisor is not guaranteed to have a multiplicative inverse.

If the ring or algebra is finite , however, then all elements a which are not zero divisors do have a left and right inverse. Distinct elements map to distinct elements, so the image consists of the same finite number of elements, and the map is necessarily surjective.
