← すべてのツール関数電卓
三角関数、対数、累乗を含む、高度な数学のためのフル機能の関数電卓。
While a standard calculator is fine for basic arithmetic, students and professionals often need to perform more complex operations involving trigonometry, logarithms, and exponential growth. Our Online Scientific Calculator provides a comprehensive set of functions in a clean, user-friendly interface. Designed to handle everything from high school geometry to university-level engineering problems, this tool supports trigonometric functions (sin, cos, tan), their inverses, natural and common logarithms, and various power and root operations. It is the perfect companion for anyone who needs a powerful mathematical workstation without carrying a physical device.
使い方
This calculator is built using a sophisticated expression evaluator that respects the mathematical order of operations (PEMDAS/BODMAS). When you enter an expression, the engine parses it into a logical tree before performing the calculations. Trigonometric functions are calculated using high-precision algorithms, and you can switch between Degrees and Radians to match your specific problem requirements.
計算式
Supports PEMDAS / BODMAS
Calculation Examples
1. **Trigonometry**: Calculate the sine of 30 degrees. In degree mode, `sin(30)` = **0.5**.
2. **Logarithms**: Find the natural log of 10. `ln(10)` ≈ **2.302**.
3. **Complex Expressions**: You can chain operations, such as `(5 * 4) + sqrt(144)`, which correctly evaluates to **32**.
Why use this tool in your daily life?
Precision is not optional in science. This service ensures you have a world-class mathematical workstation available on any device, at any time, for free, empowering you to solve complex problems without limitations.
