Frequently asked questions
▶What does the Trig Table do?
The Trig Table is an interactive trigonometry lab where you change inputs and the answers update live, helping you build intuition without doing the arithmetic by hand.
▶Who should use the Trig Table?
Students from primary to senior secondary classes, parents helping with homework, and anyone revising trigonometry can use this lab to check answers and explore "what-if" scenarios.
▶Is the Trig Table free to use?
Yes. Every lab on math.suparnpatra.com is free and runs entirely in your browser : nothing is sent to a server.
▶Does the Trig Table work offline?
Once the page is loaded, all calculations run locally in JavaScript, so you can keep using it even on a flaky connection.
▶How accurate are the results?
Results use standard JavaScript double-precision arithmetic and the textbook formula for trigonometry. We never display scientific notation : numbers are shown as ordinary decimals you can read at a glance.
