Please solve this question.
\n" ); document.write( "Q 1. Write down an equation or equations for each of the following.
\n" ); document.write( "a. A plane parallel to xy-plane at a distance of 4 units from origin on negative z-axis.
\n" ); document.write( "--------------------
\n" ); document.write( "z = -4. For all values of x and y, z is 4.
\n" ); document.write( "--------------------\r
\n" ); document.write( "\n" ); document.write( "b. A curve produced due to the intersection of a circular cylinder and yz-plane. Center of this circular cylinder is x-axis (that is, cylinder is around x-axis) and its radius is one.
\n" ); document.write( "--------------------------------
\n" ); document.write( "The intersection is a circle about the origin.
\n" ); document.write( "\"y%5E2+%2B+z%5E2+=+1\"\r
\n" ); document.write( "\n" ); document.write( "c. A curve produced due to the intersection of a sphere, center at origin and radius 3, and xy-plane.
\n" ); document.write( "----------------
\n" ); document.write( "This is also a circle about the origin. Any plane intersecting a sphere will be a circle.
\n" ); document.write( "\"x%5E2+%2B+y%5E2+=+3%5E2\"
\n" ); document.write( "\"x%5E2+%2B+y%5E2+=+9\"\r
