Real-World Examples
Example 1
Calculate the area of a circle with radius 5:
Area = π * r^2 = 3.14159 * 5^2 = 78.5398
Example 2
Find the slope of a line passing through points (1, 2) and (4, 6):
Slope = (y2 – y1) / (x2 – x1) = (6 – 2) / (4 – 1) = 1.6
Example 3
Solve the quadratic equation x^2 – 5x + 6 = 0:
x = [-b ± sqrt(b^2 – 4ac)] / (2a) = [5 ± sqrt(25 – 24)] / 2 = [5 ± 1] / 2 = 3 or 2
