PLEASE can someone help me?!!! I MUST get this VB project done for my coursework in 3 days time, and i don't understand whats being asked of me. It makes no sense. Can anyone translate it into english for me?(i mean english english, not VB language i dont know what anything means) thanks (I've got the code for a bezier curve program, but don't know what to do next: )

-----------------------
With an appropriate range of values of t and step value dt, modify the algorithm to generate parametric curves in order to generate the following:

Q.1. A cubic Bezier Curve given the following:

Possible values for the end points of the Bezier curve are:
ex1 = 0.4*Picture1.ScaleWidth ey1 = 0.8*Picture1.ScaleHeight
ex2 = 0.6*Picture1.ScaleWidth ey2 = 0.7*Picture1.ScaleHeight

Possible values for the control points of the Bezier curve are:
x1 = 0.1*Picture1.ScaleWidth y1 = 0.3*Picture1.ScaleHeight
x2 = 0.8*Picture1.ScaleWidth y2 = 0.2*Picture1.ScaleHeight

Q2. Modify the code to allow the selection of the control points for the Busier curve to be interactive.

I'll hazard a guess, do they want you to create something like what is here:

you'll need Java on your PC I think.

First you must understand what the curve is.

The reference in Response 1 and the following should help you.

Consider it a method of drawing a line from A to B with the control points controlling the direction and distance the line goes before it deviates.

The above example has the math equations.
