2. Usage Instructions

Basic Operations

  • Basic arithmetic: a+b, a−b, a×b, a÷ba + b,\, a - b,\, a \times b,\, a \div b
  • Percentage: a%a\% calculates a÷100a \div 100
  • Press = to calculate results
  • AC clears all input
  • ⌫ deletes the last character

Scientific Functions

  • Trigonometric functions: sin⁡θ, cos⁡θ, tan⁡θ\sin \theta,\, \cos \theta,\, \tan \theta
  • Logarithmic functions: ln⁡x, log⁡10x\ln x,\, \log_{10} x
  • Powers: x2, x3, xnx^2,\, x^3,\, x^n
  • Square root: x\sqrt{x}
  • Cube root: x3\sqrt[3]{x}
  • Constants: π≈3.14159, e≈2.71828\pi \approx 3.14159,\, e \approx 2.71828
  • Toggle between DEG (degrees) and RAD (radians): 180°=π rad180° = \pi \text{ rad}

Mathematical Formulas

Trigonometric Functions in Degrees:

sin⁡θ°=sin⁡(θ⋅π180)\sin \theta° = \sin(\theta \cdot \frac{\pi}{180})

Natural Logarithm:

ln⁡(ex)=x\ln(e^x) = x

Common Logarithm:

log⁡10(x)=ln⁡(x)ln⁡(10)\log_{10}(x) = \frac{\ln(x)}{\ln(10)}

Power Rules:

xn⋅xm=xn+mx^n \cdot x^m = x^{n+m}
xnxm=xn−m\frac{x^n}{x^m} = x^{n-m}
(xn)m=xn⋅m(x^n)^m = x^{n \cdot m}

5. Frequently Asked Questions

How accurate are the calculations?

Our calculator maintains high precision up to 15 decimal places for most operations. For example, π≈3.141592653589793\pi \approx 3.141592653589793

How do trigonometric calculations work?

In DEG mode, angles are in degrees (0° to 360°). In RAD mode, angles are in radians (0 to 2π2\pi). The conversion formula is: radians=degrees×π180\text{radians} = \text{degrees} \times \frac{\pi}{180}

What is the difference between ln and log?

ln⁡\ln is the natural logarithm (base ee), while log⁡\log is the common logarithm (base 10)

How do I report calculation errors?

If you encounter any calculation errors, please contact our support team with the specific calculation that caused the error.

6. Usage Tips

  • Use parentheses to group operations: (a+b)×c(a + b) \times c vs a+b×ca + b \times c
  • For complex expressions, break them down: a+bc=ac+bc\frac{a + b}{c} = \frac{a}{c} + \frac{b}{c}
  • Use scientific notation for very large or small numbers: 1.23×1061.23 \times 10^6
  • Remember that multiplication has precedence over addition: a+b×c=a+(b×c)a + b \times c = a + (b \times c)
  • Check the angle mode (DEG/RAD) when using trigonometric functions
