Study Notes
Slope Formula
- Formula: ( m = \frac{y_2 - y_1}{x_2 - x_1} )
- Determines the slope between two points on a line.
Point-Slope Form
- Formula: ( y - y_1 = m(x - x_1) )
- Used to write the equation of a line given a point and its slope.
Pythagorean Theorem
- Formula: ( a^2 + b^2 = c^2 )
- Essential for calculating the length of a side in a right triangle, where ( c ) is the hypotenuse.
Perimeter of a Triangle
- Formula: ( p = a + b + c )
- Calculates the perimeter by summing the lengths of all three sides.
Quadratic Formula
- Formula: ( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} )
- Provides solutions for ( x ) in any quadratic equation of the form ( ax^2 + bx + c = 0 ).
Discriminant
- Formula: ( b^2 - 4ac )
- Helps in identifying the number of solutions for a quadratic equation.
Midpoint Formula
- Formula: ( \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) )
- Used to calculate the midpoint of a line segment defined by two endpoints ((x_1, y_1)) and ((x_2, y_2)).
Distance Formula
- Formula: ( d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} )
- Computes the distance between two points in a Cartesian plane.
Vertex of a Parabola
- Formula: ( \left( -\frac{b}{2a}, f\left(-\frac{b}{2a}\right) \right) )
- Identifies the vertex point of a quadratic function.
Direct Variation
- Formula: ( y = kx )
- Establishes a relationship where ( y ) is directly proportional to ( x ), with ( k ) as the constant of variation.
Inverse Variation
- Formula: ( y = \frac{k}{x} )
- Defines a relationship where ( y ) varies inversely with ( x ), again with ( k ) as the constant.
Joint Variation
- Formula: ( y = kxz )
- Indicates that ( y ) varies jointly with variables ( x ) and ( z ), with ( k ) as the constant of variation.
