I don't understand why they have got [tex](e^x,p_1)[/tex] equal to [tex]\frac{1}{2}(3-e)[/tex]!
The Attempt at a Solution
[tex](e^x,p_1)=\int^1_0 e^x(x-\frac{1}{2})dx[/tex]
[tex]=\left[ xe^x-e^x- \frac{e^x}{2}\right]^1_0[/tex]
[tex]=\frac{2.7}{2}-\frac{1}{2}[/tex]
I don't get [tex](e^x,p_1)=\frac{1}{2}(3-e)[/tex].
Is there something wrong with what I'm doing?
