## Ask your question[edit | edit source]

- Choose a proper name
- Do not name your questions like, "Help! I am stuck" or "Confusing question what to do?"

- Think of what your question is about.

- For example, if your question is "The tangent PT and the normal PN to the parabola y2 = 4ax at a point P on it meet its axis at points T and N, respectively. The locus of the centroid of the triangle PTN is a parabola whose..." Let the title of your question be
**Question on parabola, tangents and axis itersection, locus of some orthocentre in it..." Give us an idea of what the question is about...!**

- Another example, if your question is "What is a nucleophile's role in SN1 reaction?" then go ahead, let the titel of your question be just that... "the role of a nucleophile in SN1 reaction.". Simple. Just use your common sense - you've got loads!

- Please DO NOT USE PUNCTUATION MARKS in your question. No exclamations, commas or slashes. Hyphens and underscores are okay.
