 Regarding vector calculus
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.......... | |
