Homework Statement
Solve [tex]\frac{1}{1}[/tex] [tex]\int^{0}_{-1}[/tex] -t e[tex]^{-j2\pi*nt}[/tex]dt
Homework Equations
So I use integration by parts
u = -t and dv = e[tex]^{-j2\pi*nt}[/tex] , du= -1 and v = [tex]\frac{1}{-j2\pi*n}[/tex]e[tex]^{-j2\pi*nt}[/tex]
The Attempt at a Solution
after integration by parts I get:
[tex]\frac{e^-j2\pi*nt}{j2pi*n}[/tex] + [tex]\frac{1}{(j2pi*n)^{2}}[/tex] [1 - e[tex]^{-j2\pi*nt}[/tex]]
So basically I am suppose to end up with [tex]\frac{1}{j2pi*n}[/tex] but it doesn't work out like it should.
Any help would be good thanks.
