This tool helps you compute the sums and differences of trigonometric functions quickly and easily.
How to Use the Calculator
To use this calculator, follow these steps:
- Enter a numeric value for ‘a’ in the first input box.
- Enter a numeric value for ‘b’ in the second input box.
- Select the desired operation from the dropdown menu. You can choose between Sum, Difference, Product, and Quotient.
- Click on the “Calculate” button to compute the result.
- The result will be displayed in the “Result” input box below the button.
How the Calculation Works
This calculator uses JavaScript to perform basic arithmetic operations based on your inputs. When you click the calculate button, the values entered in the ‘a’ and ‘b’ fields are parsed as floating-point numbers. The selected operation from the dropdown determines which arithmetic operation (sum, difference, product, or quotient) will be executed.
Limitations
- The calculator does not handle complex numbers.
- Division by zero will result in ‘Infinity’ as the result.
- Inputs are limited to numerical values; invalid inputs (e.g., alphabets) will result in ‘NaN’ (Not a Number).
- The result is displayed as a floating-point number, which may include decimal precision errors inherent in JavaScript.
