What is a Scientific Calculator?
A scientific calculator is a type of electronic calculator designed to calculate problems in science, engineering, and mathematics. It supports trigonometric functions, logarithms, exponents, and more.
How it Works
This calculator includes the following advanced functions:
- Trigonometry: sin, cos, tan, and their inverse functions (asin, acos, atan). Supports both degrees and radians.
- Logarithms: Natural logarithm (ln) and common logarithm (log base 10).
- Exponents & Roots: Square (x²), Cube (x³), Power (xʸ), Square Root (√), Cube Root (∛).
- Constants: Pi (π) and Euler's number (e).
- Other: Factorial (n!), Absolute value (|x|), Reciprocal (1/x).
Example Calculation
Enter a number and press the function button for single-operand functions (like sin, cos, log). For two-operand functions (like xʸ), enter the base, press the operator button, enter the exponent, and press equal (=).
Frequently Asked Questions
What is the difference between DEG and RAD?
DEG stands for Degrees and RAD stands for Radians. These are units of angle measurement. A full circle is 360 degrees or 2π radians.
How do I calculate log base 10?
Use the 'log' button. The 'ln' button calculates the natural logarithm (base e).
What is 'e' in math?
Euler's number (e) is a mathematical constant approximately equal to 2.71828. It is the base of the natural logarithm.
Does this calculator follow order of operations?
Yes, it follows standard mathematical order of operations (PEMDAS/BODMAS).
How to calculate factorial?
Enter a non-negative integer and press the 'n!' button. For example, 5! = 5 × 4 × 3 × 2 × 1 = 120.
