    Can someone explain to me how the bits in red are calculated with Integration, the examples are doing my head in and it would be really useful if a human could show me how they are getting the values cause mine are different.

    For example, the first circle is the integration of t times 1, from 0 to 1, which is equal to [itex]\frac{t^2}{2}|_0^1=\frac{1}{2}[/itex]. The rest are the same

    Here's a bit more detail:
    \langle 1, 1 \rangle &= \int_0^1 1\cdot 1 \, dt = t\big|_0^1 = 1 \\
    \langle t, 1 \rangle &= \int_0^1 t\cdot 1 \, dt = \left. \frac{t^2}{2}\right|_0^1 = \frac{1}{2}
    \end{align*} Those are, respectively, the denominator and numerator in the first term you circled.
