Abstract Algebra By S.K Mapa solution

IIT JAM Mathematics 2022 Short Note on Differential Equation.

Differential Equation

The most beautiful equation in mathematics.

In mathematics, Euler's identity[n 1] (also known as Euler's equation) is the equality

.    

where

e is Euler's number, the base of natural logarithms,
i is the imaginary unit, which by definition satisfies i2 = −1, and
Ī€ is pi, the ratio of the circumference of a circle to its diameter.

Euler's identity is named after the Swiss mathematician Leonhard Euler. It is considered to be an exemplar of mathematical beauty as it shows a profound connection between the most fundamental numbers in mathematics.

PROOF:

We know that,

\displaystyle{ e^{ix} = \cos(x) + i \sin(x)}

 Therefore,e^i(pi)=cos(pi)+isin(pi)

Implies,e^i(pi)=-1

      Or, e^i(pi)+1=0

                          ( Proved)

Abstract Algebra exercise 8 solution pdf. Groups. A non-empty set G is said to form a group with respect to binary composition o , if (i) G in closed under the composition, (ii) o is associative, (iii) there exists an element e in G such that aoe=eoa=e  for all a in G.  (iv) for each elementa in G, there exists an element a' in G such that a'oa=aoa'=e The group in denoted by the symbol (G.,o). The element e is said to be an identity element in the group. We shall prove that there is only one inverse element in the group and therefore e will be said to be the identity clement. The element a' is said to be an inverse of a .We shall prove that each element a has only one inverse and therefore  a' will be said to be the inverse of a . Definition,  A group (G,o) is said to be a commutative group or an the name of Norwegian mathematician N. Abel) if composition is commutative. Necessary Theorem: theorem 1.  A group (G,o) contains only one identity element. Theorem 2. ...
