Using an Excel Spreadsheet for graphs

Hello,

I want to construct graphs in quick succession and see how they behave by means of a Microsoft Excel spreadsheet.

In particular, quadratics, cubics and the trig functions so I can translate them etc.

How do I do this using an Excel spreadsheet?

I just want to key in the expression and then drag-down a box so all the values instantly appear without the tedious process of computing each x value individually.

An example on how to construct each of the above would be very helpful.

Thanks
