Homework Statement
We regard each polynomial p(t) an element of R(t) as defining a function
[itex]
p:R\rightarrow R, x \rightarrow p(x) [/itex]
prove that
[itex] g:R[t]\rightarrow R[t], p(t) \rightarrow \int_{0}^{t}p(x)dx [/itex]
defines an injective linear transformation.
Homework Equations
The Attempt at a Solution
As the function is only defined for [itex]t \geq 0 [/itex] is fair to say that when t = 0, g(T) = 0 = ker(g)
is the only vector in the kernel. and as the functions domain is well defined
then function is injective?
