COMMON QUESTIONS

Frequently Asked Questions

Trigonometric operands & decimal precision decoded
? How does the scientific calculator work?
It leverages standard JavaScript Math library functions and parsing engines to solve arithmetic and algebraic strings.
? Are my equations or calculations uploaded online?
No. All function triggers, input strings, parsing iterations, and histories are computed locally in your browser.
? What is the difference between DEG and RAD modes?
DEG calculates trigonometric functions using degrees (360° in a circle). RAD uses radians (2π in a circle) for angular measure.
? How do I calculate inverse trigonometric functions?
Click the '2nd' or 'Shift' key to toggle inverse modes like arcsin (sin⁻¹), arccos (cos⁻¹), and arctan (tan⁻¹).
? Does it support constants like Pi and Euler's number?
Yes. Dedicated keys for π (3.14159...) and e (2.71828...) allow rapid entry of mathematical constants.
? What happens if I divide by zero?
The calculator displays 'Error' or 'Infinity' immediately, preventing browser page freezes.
