Using Help

How to get started

WolframAlpha is an online tool that requires no software installation. Users simply open their browser and visit https://www.wolframalpha.com, which can be used directly. The home page has a simple input box that allows the user to enter questions or formulas. Below are the steps to do this:

1. Open the website: Type in your browser https://www.wolframalpha.com, go to the home page.
2. Enter a query: Enter a question in the input box, e.g. "Solve x^2 + 2x + 1 = 0" or "Weather in Shanghai in 2025". You can use Chinese, English or other natural languages.
3. View Results: After pressing the Enter key, the system displays the parsed interpretation of the input, the results of the calculation and the associated visualization.
4. Advanced Features: Click on the "Pro" button at the bottom of the page to learn about additional features of paid versions (such as WolframAlpha Pro), such as uploading data files or accessing more detailed problem solving steps.

Main function operation flow

1. Natural language queries

The core feature of WolframAlpha is support for natural language input. Users can enter questions like "What is the population of China?" or "What are the distances of the planets in our solar system?". The system automatically parses and extracts data from its knowledge base. For example:

• Enter "China GDP in 2025" and the system will return the latest economic data (if available) or forecasts with charts.
• Tip: The more specific the question, the more precise the answer. Avoid vague questions such as "Tell me about math", which could be changed to "What is the Fundamental Theorem of Calculus".

2. Mathematical calculations

WolframAlpha specializes in complex math problems. Users can enter formulas or questions and the system will provide answers and detailed steps. Example:

• Enter "Solve 2x + 3 = 7" and the system will return x = 2 and show the solution.
• Enter "Integrate sin(x) from 0 to pi" and the system calculates the result and displays a graph of the integral.
• Hint: Use the symbols on the keyboard (e.g. ^ for power, / for division) or type the math expression directly. The paid Pro version provides more detailed step-by-step solutions and is suitable for learning.

3. Data query and visualization

WolframAlpha draws information from multiple authoritative data sources (e.g., CIA World Factbook, USGS) and supports real-time data queries. Example:

• Enter "Distance from New York to London" and the system will return the distance in kilometers or miles and display a map.
• Enter "Periodic Table" and the system will generate an interactive periodic table, click on an element to view details.
• Tip: Use specific keywords such as "Apple stock price in 2023" to get accurate data. The visualization is available for download (Pro version).

4. Unit conversion

Unit conversion is one of WolframAlpha's useful features. When the user types "100 kilometers equals miles", the system returns 62.1371 miles and provides other relevant unit conversions. Supported units include length, weight, time, temperature, and more.

• Tip: Enter the value in the format of "value unit to unit", such as "50 degrees Celsius to degrees Fahrenheit".

5. Scientific and engineering computing

WolframAlpha supports calculations in physics, chemistry, and engineering. Example:

• Enter "Calculate F = ma, m = 2kg, a = 5m/s^2" and the system will return the force.
• Enter "balanced chemical equation C2H5OH + O2" and the system will return the balanced equation.
• Tip: Use standard terminology or symbols to ensure accurate input. pro version supports uploading of experimental data for analysis.

6. Educational support

WolframAlpha is the student's right-hand man. After entering a math or science problem, the system not only provides the answer, but also shows the steps to solve the problem. Example:

• Type "factorize x^2 - 4" and the system will return (x - 2)(x + 2) and show the factorization process.
• Tip: Click on "Show steps" to see the detailed steps (some features require a Pro account).

Advanced Features (WolframAlpha Pro)

WolframAlpha Pro is a paid version for users who need in-depth analysis. Steps to sign up for a Pro account:

1. interviews https://www.wolframalpha.com/proThe
2. Click "Sign Up" and fill in your personal information to create an account.
3. Select a subscription plan (monthly or annual) and complete the payment.
4. Log in to access advanced features such as uploading an Excel file for data analysis, downloading calculations as a PDF, or getting more detailed step-by-step solutions.

caveat

• Language Support: WolframAlpha supports multi-language input, but Chinese input may require a more specific representation to ensure accurate parsing.
• network requirement: A stable internet connection is required and some complex calculations may take a few seconds to load.
• Free vs. Paid: The free version is powerful, but the Pro version offers more interaction and export options.
