Mathematical Formulas Used in RN Calculator
The RN Calculator is based on fundamental mathematical formulas.
1. Square (x²)
Square means multiplying a number by itself.
Formula:x2=x×x
Example:
If x = 552=25
2. Square Root (√x)
Square root finds a number that produces the original value when multiplied by itself.
Formula:x
Example:25=5
Note: Square root of negative numbers is not allowed in real numbers.
3. Reciprocal (1/x)
Reciprocal is the inverse of a number.
Formula:x1
Example:
If x = 441=0.25
Note: Division by zero is undefined.
4. Cube (x³)
Cube means multiplying a number by itself three times.
Formula:x3=x×x×x
Example:
If x = 333=27
