1) Find the point on the curve of intersection of the paraboloid x^2+y^2+2z = 4 and the plane x-y+2z = 0 that is closest to the origin.

2) Find the point on the curve of intersection of the paraboloid x^2+y^2+2z = 4 and the plane x-y+2z = 0 that is farthest from the origin.


I dont necessarily need the answers , i can solve them myself if someone can tell me how in the world am I supposed to solve them. I just need an explanation cause i don't know where to start.

i don't understand this.. if > means greater than, and < means less than... how can i solve this math problem?

1.) compare using < or > 2/3 12/17

that math problem is not asking me greater than or less than, so what is it asking me to compare? i know i have to cross multiply...

I am currently taking a Algebra Elementary remedial course. I am failing most of my exams in that class and some of the guys in the class get the material fairly easy. I admit i haven't done my best to reinforce the material at home. I need to pass the exam coming up or I will be kicked out of my school which is horrible. I wish math was a human so I can kill him because he is about to ruin my life. As you can imagine I floated through the math classes in my middle school and high school. I was foolish enough to turn my back on math and now the jerk is going to ruin my dreams. I need to some how learn the material for the test so I can ace it but I don't think I can do it.


Any suggestions on what i should do?

I hate teachers and I don't like being involved with a tutor because of social problems to work out.
