Need some help again.....
Eg(1) Given Surface S: The position vector r of a point of the sphere S is given by r = xi + yj + zk subject to the constraint x^2 + y ^2 + z^2 = a^2
Can we just based on x^2 + y ^2 + z^2 = a^2 to get the parametric representation.....? Pls advise.
What abt given x+y+z = 1?
Pls advise.
Thanks..........
