1. How do I start to use the service?

To use our full service, all users must first sign up for an account by filling out our on-line registration form with your user name, email, and password. Log into your account, and you can get the full service. The 'Sign Up', 'Login', and "Account" taps are located at the navigation bar on top of our website.

2. What types of services are currently provided?

Our computing program provides an interface, from which you can perform a plenty of symbolic math calculations, including graphing functions and equations. The types of operation task range from elementary arithmetic operation, equations and inequalities, to university calculus (e.g., limit, differentiation, integration, vector algebra and calculus, and solving differential equations), linear algebra, and probability and statistics. Our featured computing interface is easy to use, and does not require computer languages and commands. You focus on learning essential math concepts and skills.

We also provide you with various exercise questions, solutions and explanations, and fact-check references, so you can verify your answer to the questions by using our computing interface, or you can review our solution to each question.

3. What graph utilities can I use?

You can use our computing interface to graph one variable or two variable functions. Graphs of one-variable functions are plan curves, and graphs of two-variable functions are three-dimensional surfaces. You may go to the subjects "Function" and "Trigonometry" for more information on graphing transformations of various functions (shifting and scaling, and reflecting). You can also graph parametric equations of one or two parameters, polar functions, and implicit equations. Some plane curves (e.g., conic sections) and space surfaces (e.g., quadratic surfaces) can be visualized by their parametrization. In addition, you can also use the "plt" module to graph pdf's, cdf's, histograms, scatter plots, boxplots, and so on for various random variables and probability distribution functions.

4. How do I effectively use or learn from the services?

Depending on how familiar you are with writing math expressions for calculation, what subject you want to learn, and what kind of goal, level or depth you want to reach. You may start with learning typing math expressions and function operations by reviewing the Instructions, or find an intersting subject from Quick Start, or dive deeper into a particular subject by clicking the "Subjects" tab on the navigation bar and choosing one from the drop-down manual.
