Regions In The PlaneTo draw a region, first you have to sketch the curve.

Page 2: 11X1 T03 05 regions in the plane (2011)

Regions In The PlaneTo draw a region, first you have to sketch the curve.1) If < or > use a dotted line

Page 3: 11X1 T03 05 regions in the plane (2011)

Regions In The PlaneTo draw a region, first you have to sketch the curve.1) If < or > use a dotted line

2) If or use a solid line

Regions In The PlaneTo draw a region, first you have to sketch the curve.1) If < or > use a dotted line

2) If or use a solid line

3) Circle the point of intersection if it is NOT included (i.e. one is < or >)

Regions In The PlaneTo draw a region, first you have to sketch the curve.1) If < or > use a dotted line

2) If or use a solid line

3) Circle the point of intersection if it is NOT included (i.e. one is < or >)

To calculate the region, test a point NOT on the curve.

2) If or use a solid line

3) Circle the point of intersection if it is NOT included (i.e. one is < or >)

To calculate the region, test a point NOT on the curve.e.g. ( ) 3i y x
