Run common scientific functions without installing software. Choose an operation, enter your value(s), and switch between degrees and radians for trig.
Pick a function or arithmetic operation. Trigonometry uses the angle mode you select below.
How to use Scientific Calculator, plus the formulas and logic behind the results.
The Scientific Calculator covers arithmetic, powers, roots, trigonometry, logarithms, exponential, reciprocal, and factorial functions in one form.
Trig: sin/cos/tan of a (converted from degrees to radians when needed)log10(a), ln(a) for a > 0; e^a; √a for a ≥ 0a! for whole numbers 0–170a ± b, a × b, a ÷ b, a^bSupported function groups
Each operation maps to a specific math function. Angle mode only affects trigonometry. Domain checks block division by zero, invalid logs, even roots of negatives, and oversized factorials.
Trigonometry uses degrees by default unless you switch to radians. Factorial accepts whole numbers from 0 to 170.
Common questions about this calculator and how to use the results.
A scientific calculator is an advanced calculator designed for mathematics, science, engineering, and other technical calculations. It can perform functions such as powers, roots, logarithms, trigonometry, and scientific notation.
Enter the numbers and mathematical operations you need, using functions such as square root, exponent, logarithm, or trigonometric functions when required. An online scientific calculator can perform these calculations directly in your browser.
A scientific calculator can perform basic arithmetic as well as powers, roots, logarithms, trigonometric functions, fractions, percentages, and other advanced mathematical operations.
A regular calculator is mainly designed for basic arithmetic, while a scientific calculator includes advanced functions such as exponents, logarithms, square roots, and trigonometry.
Enter the base number, select the power or exponent function, and enter the exponent. For example, to calculate 2⁵, enter 2, use the power function, and enter 5.
Enter the number and select the square root function. The calculator will return the square root of the value, usually as a decimal approximation when the result is not a perfect square.
Enter the number and select the logarithm function, such as log or ln. Make sure you use the appropriate logarithm base for your calculation.
Enter the angle and select sin, cos, or tan. Before calculating, make sure the calculator is set to the correct angle mode, such as degrees or radians.
Degrees and radians are two ways of measuring angles. A full circle contains 360 degrees or 2π radians. The correct mode is important when performing trigonometric calculations.
Use parentheses to control the order in which mathematical operations are performed. For example, (5 + 3) × 2 gives 16, while 5 + 3 × 2 gives 11.
Many scientific calculators can perform calculations involving fractions, including addition, subtraction, multiplication, and division. If a calculator displays decimal results, you can often convert the result to a fraction separately.
Yes. An online scientific calculator can be useful for checking calculations, practicing mathematics, completing homework, and solving problems involving advanced mathematical functions.
