    Integration.

    this is a 4 unit qsn. integration by parts: int:x^2*e^-x^2= [uv]-int:vdu given that u=x^2 and dv=e^-x^2 ([0.5x*e^-x^2]-int:-e^-x^2) [since du=2x and v=-e^-x^2/2x] ([0.5x*e^-x^2]-[e^-x^2/2x]) [apply limits and then get the answer]

    i think statistics will be the worst replacement for conics. they should remove another topic instead of conics. the only gay thing about conics is the long algebra. Good luck for the people who are gonna do it in 2-3 yrs time.
