How to build parametric graph

Follow these steps to build 3 parametric graphs on the formula  Y = x + sin( x+v ), with parameter v = 0, 1, 2:

1. Click the button   or select menu item <Analysis><Add Function>.
2. The dialog 'Build Function on Formula' will appear.
3. On a page Formula we input formula Y = u + sin( u+v ), X = u.
4. Select limits of u as range of X.
5. On a page Parameters we select 'use' parameter v.
6. Assign range of parameter v: Min=0, Max=2, Step=1.
7. On a page Line we select color and width of line.
8. Input name of graph as formula.
9. Use the button <Apply> as Preview.
10. Three graphs will 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;
