What is a Scientific Calculator?

A scientific calculator is a powerful tool for solving complex mathematical and scientific problems. Unlike basic calculators, it handles advanced functions like trigonometry, logarithms, exponents, and factorials, making it essential for students, engineers, scientists, and anyone tackling technical calculations. Our free online scientific calculator simplifies these tasks with an intuitive interface.

Key Features of Our Calculator

• Arithmetic Operations: Perform addition (+), subtraction (−), multiplication (×), division (÷), and percentages (%).
• Trigonometric Functions: Calculate sine (sin), cosine (cos), tangent (tan), and their inverses (sin⁻¹, cos⁻¹, tan⁻¹) in degrees or radians.
• Exponents and Roots: Compute powers (x², x³, x^y), square roots (√), cube roots (∛), and custom roots.
• Logarithms: Use natural logarithm (ln) and base-10 logarithm (log).
• Constants: Access π and e for precise calculations.
• Memory Functions: Store (M+), subtract (M-), recall (MR), or clear (AC) values in memory.
• History: View recent calculations to track your work.

How to Use the Calculator

Click the buttons or type to perform calculations:

• Basic Math: Enter numbers and operators (e.g., 5 + 3) and press = for the result.
• Scientific Functions: Click sin, cos, or ln, then enter a number (e.g., sin(30) for 0.5 in degrees).
• Degree/Radian Toggle: Switch modes for trigonometric calculations.
• Memory: Use M+ to store a result, MR to recall it, or AC to reset everything.
• History: Check past calculations below the buttons.
