It's NOT a "do my homework" service!

Please read the sticky post at the top of the Maths forum which explains how posters should ask questions, and the best way for people to help them, (via hints and guidance).

If you persistently ignore requests to follow the rules, then your post may get reported and your account suspended by the mods of this forum.

I'm just giving you a friendly warning before somebody else jumps in and reports you

"The maths forum is not a place to get your homework done for you; instead of providing full solutions, we will point you in the right direction on a question so that you can reach the solution yourself and hopefully help you understand the underlying concepts better in the process, which will turn out much more useful for you in the end!"

This is what it says under the sticky thing.

No probs.

We all want to help here, and we're all volunteers giving up our free time to do it. Most people can get to the end of a problem with a few nudges in the right direction but if we just dish out the answers they don't learn anything and just come back for the same sort of help a week later!
