Study Notes
Geometric Formulas
- The Pythagorean Theorem is used to find the length of the hypotenuse (c) in a right-angled triangle, where a² + b² = c².
- It is applicable to right-angled triangles, helping find the length of one side when the other two sides are known.
Quadratic Formula
- The quadratic formula is used to solve quadratic equations of the form ax² + bx + c = 0, where a, b, and c are coefficients.
- It provides both real and complex solutions, depending on the value under the square root (the discriminant), and is given by the formula x = (-b ± √(b² - 4ac)) / 2a.
Circle Properties
- The area (A) of a circle is calculated using the formula A = πr², where r is the radius of the circle.
- The constant π (pi) is approximately equal to 3.14159 and represents the ratio of a circle's circumference to its diameter.
Line Properties
- The slope (m) of a line measures its steepness and is calculated as the change in y-coordinates (y₂ - y₁) divided by the change in x-coordinates (x₂ - x₁) between two points on the line.
- It represents how much the y-value changes for a given change in the x-value.
Euler's Formula
- Euler's formula establishes a relationship between exponential and trigonometric functions, where e^(iθ) = cos(θ) + i sin(θ).
- It is fundamental in complex analysis and helps convert between exponential and trigonometric forms of complex numbers, where e is the base of the natural logarithm, i is the imaginary unit, and θ is a real number representing an angle in radians.
