Consider the paraboloid z=x^2+y^2. The plane 3x-2y+z-7=0 cuts the paraboloid, its intersection being a curve. What is the "the natural" parametrization of this curve? Hint: The curve which is cut lies above a circle in the xy-plane which you should parametrize as a function of...

We have a circle that has 270 degrees listed outside the circle at the top left. Inside the circle at the bottom right side is a an angle inside the circle with a P. Find the measure of Angle P. Would this be that we take 360-270 to get the measure of Angle P?

I have a circle with a Tangent line, DE, running along it and connecting with another line, FC, which runs through the center of the circle to the other side.I have connected the center of the circle with point E on the edge of the circle with a radius. I have labeled the ...

The most convenient way to express vectors in the two dimensional plane is in the familiar (x,y) Cartesian coordinates. However, one can express vectors in other coordinate systems as well. For example, another useful coordinate system for the plane is polar coordinates (r,&#...
