How it works
Use the on-screen keypad or your keyboard to enter complex mathematical expressions including trigonometric functions (sin, cos, tan), logarithms, square roots, exponents, and factorials. Supports memory functions (M+, M-, MR).
Why use this tool?
Ideal for students, engineers, and scientists who need a free online scientific calculator without downloading any app. Handles everything from basic arithmetic to advanced math calculations.
Frequently Asked Questions
What functions does this calculator support?
Trigonometric (sin, cos, tan, and their inverses), logarithmic (log base 10, natural log), square root, power, factorial, Pi (π), and Euler's number (e) — all standard scientific functions.
Does it support degrees and radians?
Yes. Toggle between degree and radian mode for trigonometric calculations. Make sure you're in the correct mode for your calculation — sin(90°) = 1, but sin(90 radians) ≈ 0.894.
Can I use it for exam preparation?
Yes. It matches the functionality of standard scientific calculators used in CBSE, JEE, and most competitive exams. Great for practising without a physical calculator.
Is this free?
Yes, free to use instantly with no downloads or sign-up required.
