Frequently Asked Questions (FAQ)
What is CalcPro?
CalcPro is a free online platform offering both a scientific calculator for advanced mathematical operations and a graphing calculator for visualizing functions.
Is CalcPro completely free to use?
Yes, CalcPro is entirely free to use. There are no hidden costs, subscriptions, or premium features.
What kind of calculations can the Scientific Calculator perform?
The Scientific Calculator can handle basic arithmetic (+, -, *, /), along with advanced functions like trigonometry (sin, cos, tan), logarithms (log, ln), square roots, powers, factorials, Pi (π), and Euler's number (e).
How do I use the Graphing Calculator?
Switch to the 'Graphing Calculator' mode. Enter your function using 'x' as the variable (e.g., 'x*x', 'Math.sin(x)'). Adjust the X and Y axis ranges as needed, then click 'Plot Function' to see the graph.
Can I plot multiple functions on the graph?
Currently, the graphing calculator supports plotting one function at a time. We are constantly working on updates and may add multi-function plotting in the future.
What should I do if I get an "Error" message?
If you see an "Error" message on the scientific calculator, it usually indicates an invalid operation (like division by zero or factorial of a negative number). Press the 'C' (Clear) button to reset the calculator and try again. For the graphing calculator, an error means the function could not be parsed; check your syntax.
Is CalcPro mobile-friendly?
