Eccentricity Method (or) General Method

Problem:

Draw a curve by taking distance between the fixed point (Focus) and fixed straight line (Directrix) as 50mm and the eccentricity ratio is taken as 2/3. Also draw a tangent and normal at any point on the curve.

Solution:

Oblong Method (or) Rectangular Method

Problem:

Draw an ellipse with major axis as 120mm and minor axis as 80mm using Oblong method. Also draw a tangent and normal at any point on the curve.

Solution:

Parallelogram Method

Problem:

Draw an ellipse with conjugate axis as 120mm and 80mm respectively which are inclined at 120 degrees using parallelogram method. Also draw a tangent and normal at any point on the curve.

Solution:

Concentric Circle Method

Problem:

Draw an ellipse with major axis as 120mm and minor axis as 80mm using concentric circle method. Also draw a tangent and normal at any point on the curve.

Solution:

Arc's Method

Problem:

Draw an ellipse with major axis as 120mm and minor axis as 80mm using arc's method. Also draw a tangent and normal at any point on the curve.

Solution:
