Scientific Calculator
A full-featured scientific calculator supporting trigonometric functions, logarithms, exponentials, powers, factorials and memory operations.
How to use the Scientific Calculator
- Enter your inputs into the Scientific Calculator above.
- Results update instantly as you type — no submit button needed.
- Adjust any value to see how the result changes in real time.
Key scientific functions
sin, cos, tan, log, ln, e^x, x^y, √, n!, π, e
Trig functions accept degrees or radians (toggle in calculator). Log is base 10; ln is natural log (base e). x^y raises x to the power y. Use parentheses to control order of operations.
Worked example
Calculate sin(30°) × log(1000) + e^2: sin(30°) = 0.5; log(1000) = 3; e^2 ≈ 7.389. Result: 0.5 × 3 + 7.389 = 1.5 + 7.389 = 8.889.
Frequently asked questions
Does this work in degrees or radians?
Both — toggle between modes with the DEG/RAD button. For most everyday geometry use degrees; for calculus and pure math use radians.
How do I enter scientific notation?
Use the EE or × 10^x key. 2.5 × 10^6 is entered as 2.5 EE 6, displayed as 2.5e6 in many calculators.
What is the order of operations?
Standard PEMDAS: Parentheses, Exponents, Multiplication/Division (left to right), Addition/Subtraction (left to right). The calculator enforces this automatically.
