Notice that e^x has been replaced by powers of x.
]]>For instance if we have x^2 - 2x + 1 and x = 1 anybody who has some algebra can tell us the 1^2 - 2(1) + 1 = 0.
But if I ask what is e^x when x = 1? It is not so easy. To get that we use power series ( among other methods ).
]]>Plz explain
A power series can be thought of as a polynomial of infinite degree. The field is huge so you will have to narrow the questiion down. In computation, we use them often.

Next time I wrote complete question ok
