How do you find the parameters for x,y,z and so forth. The examples in the book always use x=cos t and y=sint, but I know that there are more options. I'm just lost as to how to look at it.(adsbygoogle = window.adsbygoogle || []).push({});

For example

the line integral xy^4 ds, C is the right half of the circle x^2+y^2=16

I know this that eq. is a circle with origin as center and radius 4. So when it ways right half circle does that mean the parts of the circle in quadrants I and IV? And what parameters would you use and how would you know? What do you ask yourselves when you are working a problem like this?

Thanks
