Would anyone know how to begin a problem where a function z(x,y) is given and x(t),y(t),z(t).

Thanks!

the normal line to the surface is expressed as:

**N****i****j****k**;

**N****i****j****k**from the given line we have the symmetric equations:

which gives us:

**i****j****k** - Apr 28th 2013, 09:14 PMtopsaaRe: normal line point on surface
so we would solve for where <y,x,-1> is equal to <-2,5,3>, wouldn't that be never because of k, -1 cannot equal 3
