About Scientific Calculator

The Scientific Calculator by HyperTools is a powerful, browser-based calculator designed for students, engineers, and professionals. It supports advanced mathematical operations including trigonometry, hyperbolic functions, factorials, permutations, combinations, and memory-based calculations.

Key Features

Trigonometric functions: sin, cos, tan with RAD / DEG (DRG toggle)
Inverse and hyperbolic functions (sin⁻¹, cosh, tanh, etc.)
Factorial (n!), permutations (nPr), and combinations (nCr)
Random number and RandInt generator
Memory functions: M+, M−, MR, MC
Calculation history with quick recall
Auto-closing parentheses and live result preview

How to Use

Enter values using the on-screen buttons or keyboard. Use the DRG button to switch between Degree and Radian mode. Functions like nCr and nPr can be used in expressions such as 5 nCr 2. The history panel allows quick reuse of previous results.
