I keep thinking it must be a mistake too, but if it is a mistake then it is deliberate, as it has been repeated in a number of places. And during lectures where we go through the notes it was never picked up on.

How did you obtain the vector? You have two planes, and in \Re^{3} their intersection will be a line. I just did this question by subtracting one of the equations from a multiple of the other, and eliminating x. This then leaves an equation in terms of y and z (let's say ay +bz = c). From...

Homework Statement So using standard spherical polar co-ordinates, my notes define a sphere as r(s,t) = aCos(s)Sin(t) i + aSin(s)Sin(t) j + aCos(t) k and the normal to the surface is given by the cross product of the two partial differentials: \partialr/\partials X \partialr/dt...

Yeah it's come up in my 2nd year Quantum module. Thanks for the link, I think I'd just forgotten that, curse of the double gap year. Makes sense now, thanks again.

I agree, I think you may have written something wrong there. The easiest way is using the dot product, as (OA+OB+OC) . (OB) = 0, then you'd get two equations, one for each C co-ordinate, that'd be easy to solve. However I don't get the answer you say you were given.
