Full-featured scientific calculator for students, engineers and professionals. Trigonometry, logarithm, powers and more.
Click INV to toggle inverse functions (sin⁻¹, cos⁻¹, tan⁻¹, 10ˣ, eˣ). Switch between DEG and RAD mode for trigonometry. Use MS/MR to store and recall memory values.
Keyboard supported — type numbers and operators directly. Press Enter for equals, Escape to clear.
Our online scientific calculator handles trigonometry (sin, cos, tan and their inverses), logarithms (log base 10 and natural log), powers (x^y), square roots, cube roots, factorial (!), and memory functions. Used by students, engineers, and scientists across India for JEE, GATE, and professional calculations.
Our calculator supports both degree and radian modes. Switch between DEG and RAD mode before calculating. For JEE and school exams, most problems are in degrees. For engineering and advanced mathematics, radians are standard. sin(30°) = 0.5, cos(60°) = 0.5, tan(45°) = 1. In radians: sin(π/6) = 0.5, cos(π/3) = 0.5.
log(x) calculates logarithm base 10 (common log). ln(x) calculates natural logarithm (base e = 2.71828). These are used in compound interest formulas, pH calculations, decibel levels, and Richter scale. Example: log(1000) = 3, log(100) = 2, ln(e) = 1, ln(1) = 0. For antilog: use 10^x for antilog base 10.
