Parametric Graph
Follow these steps to build 3 parametric graphs on the formula Y = x + sin( x+v ), with parameter v = 0, 1, 2:
- Click the
 button or select menu item <Analysis><Add Function>.
- The dialog 'Build Function on Formula' appears
- On a page Formula we input formula Y = u + sin( u+v ), X = u.
- Select limits of u as range of X.
- On a page Parameters we select 'use' parameter v.
- Assign range of parameter v: Min=0, Max=2, Step=1.
- On a page Line we select color and width of line.
- Input name of graph as formula.
- Use the <Apply> button as Preview.
- Three graphs appear.
Examples:
- Y( u ) = 2+u/3+ cos( u ) * 2; X( u ) = u/5;
- Y( u ) = 5+ besselj0( u ); X( u ) = sqrt( u );
- Y( u ) = 50*normal( u, 2 ) + sin( u*3 ); X( u ) = u;
- Y( u ) = 10*normal( u, v ); X( u ) = u; v: 1,2,3;
