Homework Statement
[tex]f(x)=x^{2}[/tex] from [a,b]
Prove that [tex]F(x)=\frac{b^{3}}{2}-\frac{a^{3}}{2}[/tex]
Homework Equations
The Attempt at a Solution
Using the definition of an integral, we get:
[tex]U(f,P)=\sum^{n}_{i=1}M_{i}(t_{i}-t_{i-1})[/tex]
[tex]L(f,P)\sum^{n}_{i=1}m_{i}(t_{i}-t_{i-1})[/tex]
for the function x2, how do we find M?
I'm somewhat confused, a nudge in the right directions is welcomed.
