How the Scientific Calculator Works
Supported: sin, cos, tan, sin⁻¹, cos⁻¹, tan⁻¹, ln, log, √, ∛, xⁿ, x², 1/x, n!, nPr, nCr, π, e, |x|, mod, %, EXPCalculation Components
- Trigonometric Functions: sin, cos, tan compute ratios of right triangle sides. Inverse functions (sin⁻¹, cos⁻¹, tan⁻¹) return the angle from a ratio. Works in both DEG and RAD modes.
- Logarithmic Functions: ln computes the natural logarithm (base e ≈ 2.71828), while log computes the common logarithm (base 10). Essential for exponential growth and decay calculations.
- Exponents and Roots: x² squares a number, xⁿ raises to any power, √ finds square root, and ∛ computes cube root. The 1/x button calculates the multiplicative inverse (reciprocal).
- Combinatorics: n! computes factorial (product of integers from 1 to n). nPr calculates permutations (ordered arrangements) and nCr calculates combinations (unordered selections).
- Constants and Modifiers: π (3.14159...) and e (2.71828...) insert mathematical constants. The |x| function returns absolute value, mod performs modulo division, and % converts to percentage.
- Memory System: M+ adds current value to memory, M− subtracts from memory, MR recalls stored value, and MC clears memory. The memory indicator shows when a value is stored.
This scientific calculator covers the full mathematical syllabus required by Indian education boards including CBSE, ICSE, and various state boards. A Class 12 student in Pune studying trigonometry for JEE preparation can use this tool to verify that sin(30°) = 0.5 and cos(60°) = 0.5, while an engineering student in Chennai can calculate complex logarithmic expressions for their physics assignments. The calculator handles all edge cases including division by zero, logarithms of negative numbers, and factorial overflow with clear error messages.

What is a Scientific Calculator?
A scientific calculator is an advanced mathematical computing tool that goes far beyond basic arithmetic. While a standard calculator handles addition, subtraction, multiplication, and division, a scientific calculator provides trigonometric functions (sine, cosine, tangent), logarithmic calculations (natural log and log base 10), exponential operations, square roots, cube roots, factorials, permutations, combinations, and much more. It is an essential instrument for anyone working with mathematics beyond everyday arithmetic.
This free online scientific calculator by StoreDropship is designed for students preparing for competitive exams like JEE, NEET, CAT, GRE, and GMAT, as well as engineering professionals, physicists, data scientists, and anyone who needs precise mathematical computations. Built with expertise in mathematical computation standards, the calculator uses the same IEEE 754 double-precision floating-point arithmetic that powers professional engineering software and physical scientific calculators from brands like Casio and Texas Instruments.
The calculator supports both degree and radian angle modes, includes a memory system for storing intermediate results, maintains a calculation history for reference, and works entirely offline in your browser. Whether you are a Class 10 student in Hyderabad learning trigonometry for the first time or a research scientist in Bangalore performing complex logarithmic analysis, this tool provides the accuracy and functionality you need completely free of charge. With support for keyboard input and a mobile-responsive design, you can perform scientific calculations on any device, anywhere, anytime.
