Line

Draw Lines According To Different Equations General Form x+2y+3=0 Gradient Intercept Form y=0.5x+3 Two-Point Form (y-3)/(-1-3)=(x+3)/(2+3) Point Slope Form y-2=x-1	Perpendicular Line Passes Throuth A Given Point
Parallel Line Passes Throuth A Given Point	Relationship Of Two Lines

Circle

Draw Circles According To Different Equations Standard Form (x-1)^2+(y-2)^2=3^2 General Form x^2+y^2+x+2y-5=0 Parametric Form x=2sin(u), y=2cos(u)	Tangent Line Passes Through A Given Point On The Circle
Tangent Lines, Gradient Is Given	Circle Passes Through Three Given Points

Note: If you have installed Math Studio in your machine, you can find these examples in Samples directory in your setup path.
