# c4 - sketching parametric curves Watch

1. Hello, any tips on how to sketch parametric curves? thanks for all the help in advance!
2. Fins values of x and y using progressive values for the parameter. Plug into co-ordinates. Voila!

To find the apex of the curve (if it's one of those types) solve for p(x)=p(y).

hello , i was wondering about how to determine where the graph curves in or curves out ?
4. Easiest way I find to sketch a parametric curve is to make a quick table with 't', 'x' and 'y' as the column headers. Then taking a load of 't' values and plugging it in to your parametric equations gives you a load of 'x' and 'y' coordinates. You can then plot these and it should give you a rough idea of how the curve looks.

has some good stuff about sketching them.

Just plug in enough values for the parameter and you'll get it! I think that's the only way really. Sort of a mechanical process.
