Real-World Examples
Example 1: Converting Temperature
To convert 30 degrees Celsius to Fahrenheit, you can use the formula (C * 9/5) + 32. So, in the calculator, you would enter: (30 * 9/5) + 32
Example 2: Calculating Area
To find the area of a circle with radius 5, you can use the formula πr^2. So, in the calculator, you would enter: π * 5^2
Example 3: Solving a Quadratic Equation
To solve the quadratic equation x^2 – 5x + 6 = 0, you can use the quadratic formula x = [-b ± sqrt(b^2 – 4ac)] / (2a). So, in the calculator, you would enter: [-(-5) ± sqrt((-5)^2 – 4*1*6)] / (2*1)
