Things To Be Aware Of That Will Affect How Fast We Answer Your Question
- We do not work problems for you but, if time permits, we will try to help you understand a technique by helping you work through a specific problem.
- If you leave off any of the information listed in items 1-4 above, we will not be able to help you. Send as much detail as possible. The more detail you send, the faster and more effectively we can help you.
- Always use correct grammar, punctuation and notation or your question will be ignored.
- To enter equations, use the equation tool below.
- Since we receive many questions, we cannot guarantee any timeframe in answering your questions. We will do our best to answer them quickly. We plan to implement online, interactive tutoring sometime in the future but no date has been set for the implementation. Also, we do not work on Saturdays, so any questions submitted on Saturday will be addressed on Sunday morning at the earliest.

TeX Format Guide
This guide contains examples and templates for entering equations in TeX format. You may copy and paste these examples into the entry box above and make necessary changes for your own equations.
For a comprehensive list of symbols, see this wiki page.
type/copy this | equation | notes | ||
\frac{1}{n} | \( \displaystyle{ \frac{1}{n} } \) | both sets of braces are required | ||
x^{2} | \( \displaystyle{ x^{2} } \) | the braces are not necessary for | ||
\lim_{x \to 3}{e^{x}} | \( \displaystyle{ \lim_{x \to 3}{e^{x}} } \) | be careful to remember the \( x \to 3 \) part. | ||
\int{f(x)~dx} | \( \displaystyle{ \int{f(x)~dx} } \) | the tilde character (~) is not necessary but | ||
\int_{0}^{1}{g(x)~dx} | \( \displaystyle{ \int_{0}^{1}{g(x)~dx} } \) | underscore indicates lower limit, caret (^) indicates | ||
\sum_{n=0}^{\infty}{\frac{1}{n}} | \( \displaystyle{ \sum_{n=0}^{\infty}{\frac{1}{n}} } \) |

Greek Letters
All Greek letters are entered by preceding the letter name with a backslash, \ . For example, \alpha = \( \alpha \).
