Scientific Calculator for Science and Engineering

An online scientific calculator that performs complex mathematical and scientific calculations quickly and accurately. Supports all advanced mathematical functions including trigonometry, logarithms, powers, and factorials. Use directly in your web browser without installing any software.

Trigonometric Functions (DEG/RAD Mode)

Supports sin, cos, tan and inverse trigonometric functions asin, acos, atan. Switch between DEG (degrees) and RAD (radians) modes to calculate accurate trigonometric values based on angle units. Essential calculation features for physics, engineering, surveying, and many other fields.

Logarithm and Exponential Functions

Supports common logarithm (log₁₀), natural logarithm (ln), exponential function (exp), and power operations (xʸ, x²). Useful for calculations involving large numbers requiring scientific notation and exponential law calculations in chemistry and physics. Easy inverse logarithm calculation with the 10ˣ function.

Advanced Math Functions - Roots, Factorial, Absolute Value

Provides various advanced mathematical functions including square root (√), cube root (∛), factorial (n!), reciprocal (1/x), and absolute value (|x|). Includes practical functions such as factorials for permutation and combination calculations, and square roots and absolute values for physics calculations.

Mathematical Constants and Memory Functions

Input pi (π) and Euler's number (e) with a single button press. Memory functions (M+, MR, MC) allow you to save and reuse intermediate calculation results, enabling efficient multi-step complex calculations.

Essential Tool for Students and Professionals

Widely applicable from high school math problem solving to college calculus and engineering calculations. Supports keyboard input for fast calculations and accurately computes complex expressions with parentheses.

Frequently asked questions

What's the difference between DEG and RAD mode?

DEG calculates angles in degrees, while RAD uses radians. Always check the current mode before using sin, cos, tan, or their inverses, since the same input gives different results in each mode. Switch anytime with the DEG/RAD button.

What's the difference between log and ln?

log is the common logarithm (base 10), while ln is the natural logarithm (base e). Both are available directly on the keypad, and the 10ˣ button lets you compute the inverse of a common logarithm.

How do the memory buttons (M+, MR, MC) work?

M+ adds the current result to memory, MR recalls the stored value, and MC clears memory. This lets you stash an intermediate result during a multi-step calculation and bring it back later.

Can it handle complex expressions with parentheses?

Yes. Use the ( ) buttons to group expressions, and the calculator correctly applies operator precedence even when combining arithmetic, trig, and logarithmic functions.

When would I use the factorial (n!) function?

Factorial is commonly used in permutation, combination, and probability problems. Enter a number and press n! to instantly get the product of all integers from 1 up to that number.
