Evaluate a trigonometric expression
Use degree or radian mode before calculating sine, cosine, or tangent values.
sin(30°) + cos(60°)
Result: 1.0
Scientific Calculator
A powerful scientific calculator with advanced mathematical functions including trigonometry, logarithms, exponentials, and more. Perfect for complex calculations and mathematical analysis.
DEG
Features
- •Trigonometric functions (sin, cos, tan) and their inverses
- •Logarithmic and exponential functions
- •Power and root calculations
- •Memory functions
- •Constants (π, e)
- •Degree and radian mode support
How to Use
This scientific calculator supports both basic arithmetic operations and advanced mathematical functions. You can switch between degree and radian modes for trigonometric calculations. Use the memory functions (M+, M-, MR) to store and recall values during complex calculations.
Keyboard Shortcuts
- •Numbers (0-9) and basic operators (+, -, *, /)
- •Enter or = for calculating results
- •Backspace for deleting last input
- •Escape for clearing all (AC)
- •p or P for π (pi)
- •e or E for euler's number
- •s, c, t for sin, cos, tan (hold shift for inverse functions)
- •l for log (shift + l for natural log)
Use degree mode for most school and engineering angle problems unless the formula explicitly expects radians.
Scientific Calculator Examples
Work with powers and roots
Scientific calculators are useful when combining exponents with radicals in one expression.
5^3 - √81
Result: 116
Use logarithms for growth models
Log and natural log functions help solve exponential equations and compare scales.
log(1000) + ln(e^2)
Result: 5
Scientific Calculator FAQ
When should I use degree mode instead of radian mode?
Use degree mode for angles written as degrees, such as 30° or 45°. Use radian mode when a formula, graphing context, or math problem specifies radians.
What makes a scientific calculator different from a basic calculator?
A scientific calculator includes advanced functions such as trigonometry, logarithms, exponents, roots, constants, and memory tools in addition to basic arithmetic.
Can I use this calculator for logarithms and exponents?
Yes. It supports common logarithms, natural logs, powers, roots, and related advanced operations used in algebra, statistics, and science.
Why do memory functions matter on a scientific calculator?
Memory functions let you store intermediate values, which is helpful when you are solving long multi-step expressions or comparing several results.
