Worked Example 2

The curve [latex]C[/latex] has equation [latex]\frac{{{\left( x-2 \right)}^{2}}}{2}+{{\left( y-3 \right)}^{2}}=1[/latex] .

(i)

Sketch [latex]C[/latex],

(i)

Hence state the range of positive values of [latex]k[/latex] such that [latex]{{\left( x-2 \right)}^{2}}+{{\left( y+3 \right)}^{2}}={{k}^{2}}[/latex] intersects [latex]C[/latex] at twice.
