How I have it set up, it turns out to be the integral of 2cos(t)sin(t) -t +1 from t=0 to t=3pi/2 Mr F says: This is wrong. If you show all the details of your calculation the mistake(s) you made can be pointed out.

because I plugged the c terms into the F, then did the dot product of that with the c prime terms Mr F says: Correct method but you obviously have not done it correctly. See above.

I solved this to be -cos^2(t)-((t^2)/2)+t,

then plugged in 3pi/2

but it was wrong

any ideas why?

Thanks
