-(a) The major axis lies on the \(x\)-axis and \(a=$a1\) will have the form\[$f1=1\]. Substituting in the point \(($x1,$y1)\) gives
+(a) The $majorminor axis lies on the \(x\)-axis and \(a=$a1\) will have the form\[$f1=1\]. Substituting in the point \(($x1,$y1)\) gives
 \[$f1v=1\] which solves to give \(b^2=$bs1\).
 Our final equation is then \[1=$F1\]
