1) A geratriz perpendicular to the plan XY has equation \(\displaystyle g(1,1,0)\)?

2) How do I calculate the equation of a circumscribed cylinder into two spheres?

I have a problem can'tI find a solution:
The axis of the y is the axis hub of a circular cone that has vertex in origin. If your geratrizes forming an angle of 45° with the y-axis, find your equation

I not find a method to start

Thanks very much

1) You are going to have to speak English. You may find support in Portuguese, but it is not likely.

2) You should have read the section in your book where the problem statement was given.

3) You should learn to show your work. "No idea" simply is not acceptable.
