Why use x=2sint??

Would it be incorrect to use the x=2cost (versus the given x=2sint)? My professor instructed us to not use the given parameters in the book and to come up with our own, and I would of used x=2cost which would of changed the resulting vector-valued function (Resulting inr= 2Cos(t)i+2Sin(t)j+4Cos^{2}tk)

Thanks.
