📐 About Scientific Calculator

What it does: This Scientific Calculator is a full-featured mathematical tool designed for students, engineers, and researchers. It supports basic arithmetic, advanced trigonometric functions (sin, cos, tan and inverses), logarithms (ln, log₁₀), exponentiation, roots, constants (π, e), factorial, degree/radian mode toggle, and last answer recall (ANS). Evaluate complex expressions with parentheses seamlessly.

How it helps: Provides a distraction-free, modern interface with responsive design. Real-time expression preview, error handling, and precise evaluation via Math.js engine ensures reliable results. Ideal for homework, lab calculations, or quick scientific estimations.


❓ Frequently Asked Questions

🔹 How do I use trigonometric functions with degrees?

Toggle the DEG button (active in green). In DEG mode, sin(30) will compute 0.5. In RAD mode, trigonometric arguments are in radians. Inverse trig results (asin, acos, atan) will be returned in degrees when DEG is active, else radians.

🔹 What does the "ANS" button do?

ANS recalls the last computed result (the value shown in the RESULT field). Use it for chained calculations, e.g., 5+3=8 then × ANS → multiplies 8 by current entry.

🔹 How to use factorial and power functions?

Click fact( ) inserts "factorial(" – complete the expression inside parentheses like factorial(5). For xʸ, type base, click “xʸ”, then exponent, or use ^ symbol. x² / x³ are shortcuts.

🔹 Why do I get "Error" sometimes?

Check for mismatched parentheses, division by zero, or invalid syntax (e.g., consecutive operators). Use AC to reset and retype formula correctly.

🔹 Can I use keyboard input?

Currently optimised for click/tap but fully functional on desktop & mobile. All essential operations available via button grid.
