\n" ); document.write( "The conics form of the parabola equation (the one you'll find in advanced or older texts) is:\r
\n" ); document.write( "\n" ); document.write( " regular: $\"4p%28y+-k%29+=+%28x+-+h%29%5E2\"$
\n" ); document.write( " sideways: $\"4p%28x-h%29+=+%28y+-k%29%5E2\"$ .......... since focus is at ( $\"4\"$ , $\"0\"$ ), you need this formula\r
\n" ); document.write( "\n" ); document.write( " $\"4p%28x-h%29+=+%28y+-k%29%5E2\"$ ............since vertex is the origin we have
\n" ); document.write( " $\"4p%28x-0%29+=+%28y+-0%29%5E2\"$
\n" ); document.write( " $\"4px+=+y+%5E2\"$ ............since focus is at ( $\"4\"$ , $\"0\"$ )and $\"p\"$ is the distance between the vertex and the focus, $\"p=4\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"4%2A4x+=+y+%5E2\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"y+%5E2=16x+\"$ \r
