hi, I'm stuck on a curve parametrisation question. It reads as follows:(adsbygoogle = window.adsbygoogle || []).push({});

"Consider the two spherical surfaces [itex]x^2 + y^2 + z^2 = 4[/itex] and [itex]x^2 + y^2 + (z - 1)^2 = 2[/itex]. Let [itex]\gamma[/itex] be the curve in which they meet. Evaluate the line integral x over gamma "

So far I have let the two surfaces equal one another and found that [itex] z = \frac {3} {2}[/itex]. Then I substituted this back in to the equation above and found that [itex] y = \sqrt {\frac {7} {4} - x^2} [/itex].

I don't quite know how to take this further and parametrise the curve between the two spheres.

I'm not sure if this is the right way of doing this. Any help or comments would be appreciated.

Thanks
