What Does the Improper Integral \int^{\infty}_{o}\frac{sinx}{x} Mean?

[twalker40]

1. Let F(x)= $$\int^{x}_{0} \frac{sint}{t}$$ and f(x) = $$\frac{sinx}{x}$$. If x approaches infinity, F(x) approaches $$\pi/2$$. So, Explain what does this mean for the improper integral $$\int^{\infty}_{o}\frac{sinx}{x}$$

What is the definition of
[tex]\int_a^\infty f(x) dx[/itex]?
