For engineering calculations, use WolframAlpha. It computes answers with the Mathematica engine instead of predicting text, so the numbers, integrals and unit conversions come from actual calculation. Use ChatGPT to explain concepts and to write Python code for repetitive calculations, and check its numbers in WolframAlpha or by running the code. For worked steps, WolframAlpha Pro, Symbolab and Photomath all show them.
Each tool does a different job. A language model can explain the second law of thermodynamics well and still get the arithmetic of an entropy change wrong, so pair it with a solver. For more tools and guides, see our study resources for engineering students.
WolframAlpha is not a chatbot. It is built on Mathematica and calculates answers from curated data and math algorithms, so it does not guess. The free version gives answers. WolframAlpha Pro adds step-by-step solutions, photo input in the mobile app, file upload and longer computation time.
Don't trust ChatGPT's mental arithmetic for a final answer. Ask it to write Python instead, using libraries like NumPy and SciPy, and run the code yourself or in ChatGPT. Then the numbers come from the code, and you can read the code to check the method.
Use ChatGPT to automate the "grunt work." If you have 50 different load cases for a beam analysis, do not calculate them manually. Ask ChatGPT to write a Python script that iterates through the values and outputs a CSV file. You then spend your time checking the results instead of doing the arithmetic.
Symbolab, owned by Learneo (Course Hero's parent), shows step-by-step solutions. Use it when you need to see each algebra or calculus step to check your own working.
Mathway covers algebra, calculus, statistics and chemistry problems. It is handy for quick checks of simple homework, but it does less than WolframAlpha for engineering-level problems.
Photomath, owned by Google since 2023, scans a printed or handwritten problem with your phone camera and shows the steps to solve it. The app is mostly free. Photomath Plus adds word problems and textbook solutions. It is best for algebra and calculus, not full engineering problems.
Different engineering branches have different calculation needs. A civil engineer cares about static equilibrium, while an electrical engineer cares about complex numbers and phasors.
In civil engineering, you deal with a lot of lookup tables and standard codes (like ACI or AISC). AI is helpful here for summarizing these codes, but for the actual calcs, use tools that handle matrices well. Beam deflection and truss analysis are essentially large systems of linear equations. WolframAlpha is excellent for solving these matrices quickly.
Electrical engineering is heavy on complex numbers (imaginary units) and differential equations. When solving RLC circuits, you often end up with second order differential equations. Symbolab is particularly useful here because it shows the characteristic equation and the homogeneous solution steps, which are usually where students get stuck.
Thermodynamics and Heat Transfer involve a lot of iterative solving. For example, finding the temperature of a gas given its enthalpy requires looking up values in a table and interpolating. A language model may misremember table values, so take the values from your steam tables yourself and ask ChatGPT to write a Python function that interpolates between them.
You can't use these tools in the exam. If they solve your homework for you, you won't be able to solve the same problems on paper.
So solve each problem yourself first and use the tools to check it. When a tool like Symbolab shows a step you didn't understand, write that step or formula down as a flashcard, and review it until you can do it unaided.
StudyCards AI can turn your engineering lecture notes and PDFs into flashcards of the formulas and the conditions they apply under. You can export the cards to Anki and review them on a spaced schedule before the exam.

No, not for direct arithmetic or complex symbolic math. ChatGPT is a language model and can hallucinate numbers. It is more reliable when it writes Python code that you run and check. Always use a computational engine like WolframAlpha for final numerical verification.
WolframAlpha's free version gives answers to most undergraduate engineering problems. Its step-by-step solutions need WolframAlpha Pro. Photomath is mostly free and shows steps for problems you scan with your phone.
Yes. WolframAlpha and Symbolab both solve ordinary differential equations. Give them the initial conditions and they return the particular solution as well as the general one.
Use AI to verify your work, not to do it. Try to solve the problem manually first, then use the AI to find where you went wrong. Turn the formulas and steps you got wrong into flashcards, so you can do the calculations without help in the exam.
