Scientific Calculator Pro

Scientific Calculator Pro is a powerful, multi-module scientific calculator designed for students, engineers, and scientists.

CALCULATOR
• Trigonometric functions (sin, cos, tan) — degrees or radians
• Inverse trigonometric functions (sin⁻¹, cos⁻¹, tan⁻¹)
• Logarithms (log, ln) and exponential functions (eˣ, 10ˣ)
• Factorial (n!), permutation (nPr), and combination (nCr)
• Exponentiation (xʸ), n-th • Root (ʸ√x), square root, inverse (1/x)
• Memory functions (M+, M−, MR, MC)
• Casio-inspired dot matrix LCD display

ASTRONOMY MODULE
• Gravitational acceleration calculation (for any celestial body)
• Schwarzschild radius — black hole event horizon
• Escape velocity calculation
• Hubble's Law — recession velocity and distance
• Kepler's Third Law — orbital period

ELECTRONICS MODULE
• Ohm's Law (V = IR)
• Electrical power (P = VI)
• RC circuit (time constant, charge/discharge curves)
• LC resonance frequency
• Voltage divider

UNIT CONVERTER
• Length, mass, temperature, pressure and more

DESIGN
Stylish dark interface with Casio ClassWiz-inspired dot matrix LCD display. All calculations are performed entirely on the device — no internet connection is required.
